Pali Rohár	0c6cfc109e	serial: mvebu-uart: fix tx lost characters at power off ... commit 54ca955b5a upstream. Commit c685af1108 ("serial: mvebu-uart: fix tx lost characters") fixed tx lost characters at low baud rates but started causing tx lost characters when kernel is going to power off or reboot. TX_EMP tells us when transmit queue is empty therefore all characters were transmitted. TX_RDY tells us when CPU can send a new character. Therefore we need to use different check prior transmitting new character and different check after all characters were sent. This patch splits polling code into two functions: wait_for_xmitr() which waits for TX_RDY and wait_for_xmite() which waits for TX_EMP. When rebooting A3720 platform without this patch on UART is print only: [ 42.699� And with this patch on UART is full output: [ 39.530216] reboot: Restarting system Fixes: c685af1108 ("serial: mvebu-uart: fix tx lost characters") Signed-off-by: Pali Rohár <pali@kernel.org> Cc: stable <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20201223191931.18343-1-pali@kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2021-01-27 11:05:40 +01:00

Alexey Kardashevskiy	7a3c3a1c67	serial_core: Check for port state when tty is in error state ... commit 2f70e49ed8 upstream. At the moment opening a serial device node (such as /dev/ttyS3) succeeds even if there is no actual serial device behind it. Reading/writing/ioctls fail as expected because the uart port is not initialized (the type is PORT_UNKNOWN) and the TTY_IO_ERROR error state bit is set fot the tty. However setting line discipline does not have these checks 8250_port.c (8250 is the default choice made by univ8250_console_init()). As the result of PORT_UNKNOWN, uart_port::iobase is NULL which a platform translates onto some address accessing which produces a crash like below. This adds tty_port_initialized() to uart_set_ldisc() to prevent the crash. Found by syzkaller.

Alexander Sverdlin	fcf9b7fbc2	serial: 8250_omap: Avoid FIFO corruption caused by MDR1 access ... commit d96f04d347 upstream. It has been observed that once per 300-1300 port openings the first transmitted byte is being corrupted on AM3352 ("v" written to FIFO appeared as "e" on the wire). It only happened if single byte has been transmitted right after port open, which means, DMA is not used for this transfer and the corruption never happened afterwards. Therefore I've carefully re-read the MDR1 errata (link below), which says "when accessing the MDR1 registers that causes a dummy under-run condition that will freeze the UART in IrDA transmission. In UART mode, this may corrupt the transferred data". Strictly speaking, omap_8250_mdr1_errataset() performs a read access and if the value is the same as should be written, exits without errata-recommended FIFO reset. A brief check of the serial_omap_mdr1_errataset() from the competing omap-serial driver showed it has no read access of MDR1. After removing the read access from omap_8250_mdr1_errataset() the data corruption never happened any more.

Jann Horn	361e822b7d	tty: Fix ->session locking ... commit c8bcd9c5be upstream. Currently, locking of ->session is very inconsistent; most places protect it using the legacy tty mutex, but disassociate_ctty(), __do_SAK(), tiocspgrp() and tiocgsid() don't. Two of the writers hold the ctrl_lock (because they already need it for ->pgrp), but __proc_set_tty() doesn't do that yet. On a PREEMPT=y system, an unprivileged user can theoretically abuse this broken locking to read 4 bytes of freed memory via TIOCGSID if tiocgsid() is preempted long enough at the right point. (Other things might also go wrong, especially if root-only ioctls are involved; I'm not sure about that.) Change the locking on ->session such that: - tty_lock() is held by all writers: By making disassociate_ctty() hold it. This should be fine because the same lock can already be taken through the call to tty_vhangup_session(). The tricky part is that we need to shorten the area covered by siglock to be able to take tty_lock() without ugly retry logic; as far as I can tell, this should be fine, since nothing in the signal_struct is touched in the `if (tty)` branch. - ctrl_lock is held by all writers: By changing __proc_set_tty() to hold the lock a little longer. - All readers that aren't holding tty_lock() hold ctrl_lock: By adding locking to tiocgsid() and __do_SAK(), and expanding the area covered by ctrl_lock in tiocspgrp().

Jann Horn	13f10a7809	tty: Fix ->pgrp locking in tiocspgrp() ... commit 54ffccbf05 upstream. tiocspgrp() takes two tty_struct pointers: One to the tty that userspace passed to ioctl() (`tty`) and one to the TTY being changed (`real_tty`). These pointers are different when ioctl() is called with a master fd. To properly lock real_tty->pgrp, we must take real_tty->ctrl_lock. This bug makes it possible for racing ioctl(TIOCSPGRP, ...) calls on both sides of a PTY pair to corrupt the refcount of `struct pid`, leading to use-after-free errors.

Claire Chang	18f5757d7f	serial: 8250_mtk: Fix uart_get_baud_rate warning ... commit 912ab37c79 upstream. Mediatek 8250 port supports speed higher than uartclk / 16. If the baud rates in both the new and the old termios setting are higher than uartclk / 16, the WARN_ON in uart_get_baud_rate() will be triggered. Passing NULL as the old termios so uart_get_baud_rate() will use uartclk / 16 - 1 as the new baud rate which will be replaced by the original baud rate later by tty_termios_encode_baud_rate() in mtk8250_set_termios().

Obviously, this will cause an out-of-bounds read, because we can > access a smaller vc_font.data with a larger vc_font.height. Further there was only one user ever. - Android's loadfont, busybox and console-tools only ever use OP_GET and OP_SET - fbset documentation only mentions the kernel cmdline font: option, not anything else. - systemd used OP_COPY before release 232 published in Nov 2016 Now unfortunately the crucial report seems to have gone down with gmane, and the commit message doesn't say much. But the pull request hints at OP_COPY being broken https://github.com/systemd/systemd/pull/3651 So in other words, this never worked, and the only project which foolishly every tried to use it, realized that rather quickly too. Instead of trying to fix security issues here on dead code by adding missing checks, fix the entire thing by removing the functionality. Note that systemd code using the OP_COPY function ignored the return value, so it doesn't matter what we're doing here really - just in case a lone server somewhere happens to be extremely unlucky and running an affected old version of systemd. The relevant code from font_copy_to_all_vcs() in systemd was: /* copy font from active VT, where the font was uploaded to */ cfo.op = KD_FONT_OP_COPY; cfo.height = vcs.v_active-1; /* tty1 == index 0 */ (void) ioctl(vcfd, KDFONTOP, &cfo); Note this just disables the ioctl, garbage collecting the now unused callbacks is left for -next. v2: Tetsuo found the old mail, which allowed me to find it on another archive.

Linus Torvalds	619e366268	tty: make FONTX ioctl use the tty pointer they were actually passed ... commit 90bfdeef83 upstream. Some of the font tty ioctl's always used the current foreground VC for their operations. Don't do that then. This fixes a data race on fg_console. Side note: both Michael Ellerman and Jiri Slaby point out that all these ioctls are deprecated, and should probably have been removed long ago, and everything seems to be using the KDFONTOP ioctl instead. In fact, Michael points out that it looks like busybox's loadfont program seems to have switched over to using KDFONTOP exactly _because_ of this bug (ahem.. 12 years ago ;-).

Jiri Slaby	7e3ba72e5b	vt: keyboard, extend func_buf_lock to readers ... commit 82e61c3909 upstream. Both read-side users of func_table/func_buf need locking. Without that, one can easily confuse the code by repeatedly setting altering strings like: while (1) for (a = 0; a < 2; a++) { struct kbsentry kbs = {}; strcpy((char *)kbs.kb_string, a ? ".\n" : "88888\n"); ioctl(fd, KDSKBSENT, &kbs); } When that program runs, one can get unexpected output by holding F1 (note the unxpected period on the last line): . 88888 .8888 So protect all accesses to 'func_table' (and func_buf) by preexisting 'func_buf_lock'. It is easy in 'k_fn' handler as 'puts_queue' is expected not to sleep. On the other hand, KDGKBSENT needs a local (atomic) copy of the string because copy_to_user can sleep. Use already allocated, but unused 'kbs->kb_string' for that purpose. Note that the program above needs at least CAP_SYS_TTY_CONFIG. This depends on the previous patch and on the func_buf_lock lock added in commit 46ca3f735f (tty/vt: fix write/write race in ioctl(KDSKBSENT) handler) in 5.2. Likely fixes CVE-2020-25656.

Jiri Slaby	20cf3fcdd6	vt: keyboard, simplify vt_kdgkbsent ... commit 6ca03f9052 upstream. Use 'strlen' of the string, add one for NUL terminator and simply do 'copy_to_user' instead of the explicit 'for' loop. This makes the KDGKBSENT case more compact. The only thing we need to take care about is NULL 'func_table[i]'. Use an empty string in that case. The original check for overflow could never trigger as the func_buf strings are always shorter or equal to 'struct kbsentry's.

Peter Zijlstra	ad1e8fc2a5	serial: pl011: Fix lockdep splat when handling magic-sysrq interrupt ... commit 534cf755d9 upstream. Issuing a magic-sysrq via the PL011 causes the following lockdep splat, which is easily reproducible under QEMU: | sysrq: Changing Loglevel | sysrq: Loglevel set to 9 | | ====================================================== | WARNING: possible circular locking dependency detected | 5.9.0-rc7 #1 Not tainted | ------------------------------------------------------ | systemd-journal/138 is trying to acquire lock: | ffffab133ad950c0 (console_owner){-.-.}-{0:0}, at: console_lock_spinning_enable+0x34/0x70 | | but task is already holding lock: | ffff0001fd47b098 (&port_lock_key){-.-.}-{2:2}, at: pl011_int+0x40/0x488 | | which lock already depends on the new lock. [...] | Possible unsafe locking scenario: | | CPU0 CPU1 | ---- ---- | lock(&port_lock_key); | lock(console_owner); | lock(&port_lock_key); | lock(console_owner); | | *** DEADLOCK *** The issue being that CPU0 takes 'port_lock' on the irq path in pl011_int() before taking 'console_owner' on the printk() path, whereas CPU1 takes the two locks in the opposite order on the printk() path due to setting the "console_owner" prior to calling into into the actual console driver. Fix this in the same way as the msm-serial driver by dropping 'port_lock' before handling the sysrq.

Tyrel Datwyler	51ba64f0b3	tty: hvcs: Don't NULL tty->driver_data until hvcs_cleanup() ... [ Upstream commit 63ffcbdad7 ] The code currently NULLs tty->driver_data in hvcs_close() with the intent of informing the next call to hvcs_open() that device needs to be reconfigured. However, when hvcs_cleanup() is called we copy hvcsd from tty->driver_data which was previoulsy NULLed by hvcs_close() and our call to tty_port_put(&hvcsd->port) doesn't actually do anything since &hvcsd->port ends up translating to NULL by chance. This has the side effect that when hvcs_remove() is called we have one too many port references preventing hvcs_destuct_port() from ever being called. This also prevents us from reusing the /dev/hvcsX node in a future hvcs_probe() and we can eventually run out of /dev/hvcsX devices. Fix this by waiting to NULL tty->driver_data in hvcs_cleanup().

Jonathan Bakker	08cfb31399	tty: serial: samsung: Correct clock selection logic ... [ Upstream commit 7d31676a8d ] Some variants of the samsung tty driver can pick which clock to use for their baud rate generation. In the DT conversion, a default clock was selected to be used if a specific one wasn't assigned and then a comparison of which clock rate worked better was done. Unfortunately, the comparison was implemented in such a way that only the default clock was ever actually compared. Fix this by iterating through all possible clocks, except when a specific clock has already been picked via clk_sel (which is only possible via board files).

Vignesh Raghavendra	2019176020	serial: 8250_port: Don't service RX FIFO if throttled ... [ Upstream commit f19c3f6c81 ] When port's throttle callback is called, it should stop pushing any more data into TTY buffer to avoid buffer overflow. This means driver has to stop HW from receiving more data and assert the HW flow control. For UARTs with auto HW flow control (such as 8250_omap) manual assertion of flow control line is not possible and only way is to allow RX FIFO to fill up, thus trigger auto HW flow control logic. Therefore make sure that 8250 generic IRQ handler does not drain data when port is stopped (i.e UART_LSR_DR is unset in read_status_mask). Not servicing, RX FIFO would trigger auto HW flow control when FIFO occupancy reaches preset threshold, thus halting RX. Since, error conditions in UART_LSR register are cleared just by reading the register, data has to be drained in case there are FIFO errors, else error information will lost.

Lukas Wunner	8b4846ac1a	serial: 8250: Avoid error message on reprobe ... commit e0a851fe6b upstream. If the call to uart_add_one_port() in serial8250_register_8250_port() fails, a half-initialized entry in the serial_8250ports[] array is left behind. A subsequent reprobe of the same serial port causes that entry to be reused. Because uart->port.dev is set, uart_remove_one_port() is called for the half-initialized entry and bails out with an error message: bcm2835-aux-uart 3f215040.serial: Removing wrong port: (null) != (ptrval) The same happens on failure of mctrl_gpio_init() since commit 4a96895f74 ("tty/serial/8250: use mctrl_gpio helpers"). Fix by zeroing the uart->port.dev pointer in the probe error path. The bug was introduced in v2.6.10 by historical commit befff6f5bf5f ("[SERIAL] Add new port registration/unregistration functions."): https://git.kernel.org/tglx/history/c/befff6f5bf5f The commit added an unconditional call to uart_remove_one_port() in serial8250_register_port(). In v3.7, commit 835d844d1a ("8250_pnp: do pnp probe before legacy probe") made that call conditional on uart->port.dev which allows me to fix the issue by zeroing that pointer in the error path. Thus, the present commit will fix the problem as far back as v3.7 whereas still older versions need to also cherry-pick 835d844d1a.

These serial ports are exposed by the OOB-management-engine on RealManage-enabled network cards (e.g. AMD DASH enabled systems using Realtek cards). Because these have 3 BARs, they fail the "num_iomem <= 1" check in serial_pci_guess_board. I've manually checked the two IOMEM regions and BAR 2 doesn't seem to respond to reads, but BAR 4 seems to be an MMIO version of the IO ports (untested). With this change, the ports are detected: 0000:02:00.1: ttyS0 at I/O 0x2200 (irq = 82, base_baud = 115200) is a 16550A 0000:02:00.2: ttyS1 at I/O 0x2100 (irq = 55, base_baud = 115200) is a 16550A lspci output: 02:00.1 0700: 10ec:816a (rev 0e) (prog-if 02 [16550]) Subsystem: 17aa:5082 Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort+ <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin B routed to IRQ 82 IOMMU group: 11 Region 0: I/O ports at 2200 [size=256] Region 2: Memory at fd715000 (64-bit, non-prefetchable) [size=4K] Region 4: Memory at fd704000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=375mA PME(D0+,D1+,D2+,D3hot+,D3cold+) Status: D0 NoSoftRst+ PME-Enable- DSel=0 DScale=0 PME- Capabilities: [50] MSI: Enable- Count=1/1 Maskable- 64bit+ Address: 0000000000000000 Data: 0000 Capabilities: [70] Express (v2) Endpoint, MSI 01 DevCap: MaxPayload 128 bytes, PhantFunc 0, Latency L0s unlimited, L1 <64us ExtTag- AttnBtn- AttnInd- PwrInd- RBE+ FLReset- SlotPowerLimit 0.000W DevCtl: CorrErr- NonFatalErr- FatalErr- UnsupReq- RlxdOrd+ ExtTag- PhantFunc- AuxPwr- NoSnoop- MaxPayload 128 bytes, MaxReadReq 512 bytes DevSta: CorrErr+ NonFatalErr- FatalErr- UnsupReq+ AuxPwr+ TransPend- LnkCap: Port #0, Speed 2.5GT/s, Width x1, ASPM L0s L1, Exit Latency L0s unlimited, L1 <64us ClockPM+ Surprise- LLActRep- BwNot- ASPMOptComp+ LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+ ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt- LnkSta: Speed 2.5GT/s (ok), Width x1 (ok) TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt- DevCap2: Completion Timeout: Range ABCD, TimeoutDis+ NROPrPrP- LTR+ 10BitTagComp- 10BitTagReq- OBFF Via message/WAKE#, ExtFmt- EETLPPrefix- EmergencyPowerReduction Not Supported, EmergencyPowerReductionInit- FRS- TPHComp- ExtTPHComp- AtomicOpsCap: 32bit- 64bit- 128bitCAS- DevCtl2: Completion Timeout: 50us to 50ms, TimeoutDis- LTR- OBFF Disabled, AtomicOpsCtl: ReqEn- LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete- EqualizationPhase1- EqualizationPhase2- EqualizationPhase3- LinkEqualizationRequest- Retimer- 2Retimers- CrosslinkRes: unsupported Capabilities: [b0] MSI-X: Enable- Count=4 Masked- Vector table: BAR=4 offset=00000000 PBA: BAR=4 offset=00000800 Capabilities: [d0] Vital Product Data Not readable Capabilities: [100 v2] Advanced Error Reporting UESta: DLP- SDES- TLP- FCP- CmpltTO- CmpltAbrt- UnxCmplt- RxOF- MalfTLP- ECRC- UnsupReq- ACSViol- UEMsk: DLP- SDES- TLP- FCP- CmpltTO- CmpltAbrt- UnxCmplt- RxOF- MalfTLP- ECRC- UnsupReq- ACSViol- UESvrt: DLP+ SDES+ TLP- FCP+ CmpltTO- CmpltAbrt- UnxCmplt- RxOF+ MalfTLP+ ECRC- UnsupReq- ACSViol- CESta: RxErr- BadTLP- BadDLLP- Rollover- Timeout- AdvNonFatalErr+ CEMsk: RxErr- BadTLP- BadDLLP- Rollover- Timeout- AdvNonFatalErr+ AERCap: First Error Pointer: 00, ECRCGenCap+ ECRCGenEn- ECRCChkCap+ ECRCChkEn- MultHdrRecCap- MultHdrRecEn- TLPPfxPres- HdrLogCap- HeaderLog: 00000000 00000000 00000000 00000000 Capabilities: [160 v1] Device Serial Number 00-00-00-00-00-00-00-00 Capabilities: [170 v1] Latency Tolerance Reporting Max snoop latency: 0ns Max no snoop latency: 0ns Capabilities: [178 v1] L1 PM Substates L1SubCap: PCI-PM_L1.2+ PCI-PM_L1.1+ ASPM_L1.2+ ASPM_L1.1+ L1_PM_Substates+ PortCommonModeRestoreTime=150us PortTPowerOnTime=150us L1SubCtl1: PCI-PM_L1.2- PCI-PM_L1.1- ASPM_L1.2- ASPM_L1.1- T_CommonMode=0us LTR1.2_Threshold=0ns L1SubCtl2: T_PwrOn=10us 02:00.2 0700: 10ec:816b (rev 0e) [...same...] Signed-off-by: Tobias Diedrich <tobiasdiedrich@gmail.com> Cc: stable <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20200914173628.GA22508@yamamaya.is-a-geek.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2020-09-23 12:11:01 +02:00

John Stultz	ee385b4108	tty: serial: qcom_geni_serial: Drop __init from qcom_geni_console_setup ... [ Upstream commit 975efc66d4 ] When booting with heavily modularized config, the serial console may not be able to load until after init when modules that satisfy needed dependencies have time to load. Unfortunately, as qcom_geni_console_setup is marked as __init, the function may have been freed before we get to run it, causing boot time crashes such as: [ 6.469057] Unable to handle kernel paging request at virtual address ffffffe645d4e6cc [ 6.481623] Mem abort info: [ 6.484466] ESR = 0x86000007 [ 6.487557] EC = 0x21: IABT (current EL), IL = 32 bits [ 6.492929] SET = 0, FnV = 0g [ 6.496016] EA = 0, S1PTW = 0 [ 6.499202] swapper pgtable: 4k pages, 39-bit VAs, pgdp=000000008151e000 [ 6.501286] ufshcd-qcom 1d84000.ufshc: ufshcd_print_pwr_info:[RX, TX]: gear=[3, 3], lane[2, 2], pwr[FAST MODE, FAST MODE], rate = 2 [ 6.505977] [ffffffe645d4e6cc] pgd=000000017df9f003, p4d=000000017df9f003, pud=000000017df9f003, pmd=000000017df9c003, pte=0000000000000000 [ 6.505990] Internal error: Oops: 86000007 [#1] PREEMPT SMP [ 6.505995] Modules linked in: zl10353 zl10039 zl10036 zd1301_demod xc5000 xc4000 ves1x93 ves1820 tuner_xc2028 tuner_simple tuner_types tua9001 tua6100 1 [ 6.506152] isl6405 [ 6.518104] ufshcd-qcom 1d84000.ufshc: ufshcd_find_max_sup_active_icc_level: Regulator capability was not set, actvIccLevel=0 [ 6.530549] horus3a helene fc2580 fc0013 fc0012 fc0011 ec100 e4000 dvb_pll ds3000 drxk drxd drx39xyj dib9000 dib8000 dib7000p dib7000m dib3000mc dibx003 [ 6.624271] CPU: 7 PID: 148 Comm: kworker/7:2 Tainted: G W 5.8.0-mainline-12021-g6defd37ba1cd #3455 [ 6.624273] Hardware name: Thundercomm Dragonboard 845c (DT) [ 6.624290] Workqueue: events deferred_probe_work_func [ 6.624296] pstate: 40c00005 (nZcv daif +PAN +UAO BTYPE=--) [ 6.624307] pc : qcom_geni_console_setup+0x0/0x110 [ 6.624316] lr : try_enable_new_console+0xa0/0x140 [ 6.624318] sp : ffffffc010843a30 [ 6.624320] x29: ffffffc010843a30 x28: ffffffe645c3e7d0 [ 6.624325] x27: ffffff80f8022180 x26: ffffffc010843b28 [ 6.637937] x25: 0000000000000000 x24: ffffffe6462a2000 [ 6.637941] x23: ffffffe646398000 x22: 0000000000000000 [ 6.637945] x21: 0000000000000000 x20: ffffffe6462a5ce8 [ 6.637952] x19: ffffffe646398e38 x18: ffffffffffffffff [ 6.680296] x17: 0000000000000000 x16: ffffffe64492b900 [ 6.680300] x15: ffffffe6461e9d08 x14: 69202930203d2064 [ 6.680305] x13: 7561625f65736162 x12: 202c363331203d20 [ 6.696434] x11: 0000000000000030 x10: 0101010101010101 [ 6.696438] x9 : 4d4d20746120304d x8 : 7f7f7f7f7f7f7f7f [ 6.707249] x7 : feff4c524c787373 x6 : 0000000000008080 [ 6.707253] x5 : 0000000000000000 x4 : 8080000000000000 [ 6.707257] x3 : 0000000000000000 x2 : ffffffe645d4e6cc [ 6.744223] qcom_geni_serial 898000.serial: dev_pm_opp_set_rate: failed to find OPP for freq 102400000 (-34) [ 6.744966] x1 : fffffffefe74e174 x0 : ffffffe6462a5ce8 [ 6.753580] qcom_geni_serial 898000.serial: dev_pm_opp_set_rate: failed to find OPP for freq 102400000 (-34) [ 6.761634] Call trace: [ 6.761639] qcom_geni_console_setup+0x0/0x110 [ 6.761645] register_console+0x29c/0x2f8 [ 6.767981] Bluetooth: hci0: Frame reassembly failed (-84) [ 6.775252] uart_add_one_port+0x438/0x500 [ 6.775258] qcom_geni_serial_probe+0x2c4/0x4a8 [ 6.775266] platform_drv_probe+0x58/0xa8 [ 6.855359] really_probe+0xec/0x398 [ 6.855362] driver_probe_device+0x5c/0xb8 [ 6.855367] __device_attach_driver+0x98/0xb8 [ 7.184945] bus_for_each_drv+0x74/0xd8 [ 7.188825] __device_attach+0xec/0x148 [ 7.192705] device_initial_probe+0x24/0x30 [ 7.196937] bus_probe_device+0x9c/0xa8 [ 7.200816] deferred_probe_work_func+0x7c/0xb8 [ 7.205398] process_one_work+0x20c/0x4b0 [ 7.209456] worker_thread+0x48/0x460 [ 7.213157] kthread+0x14c/0x158 [ 7.216432] ret_from_fork+0x10/0x18 [ 7.220049] Code: bad PC value [ 7.223139] ---[ end trace 73f3b21e251d5a70 ]--- Thus this patch removes the __init avoiding crash in such configs.

Sergey Senozhatsky	2eb35a11bb	serial: 8250: change lock order in serial8250_do_startup() ... commit 205d300aea upstream. We have a number of "uart.port->desc.lock vs desc.lock->uart.port" lockdep reports coming from 8250 driver; this causes a bit of trouble to people, so let's fix it. The problem is reverse lock order in two different call paths: chain #1: serial8250_do_startup() spin_lock_irqsave(&port->lock); disable_irq_nosync(port->irq); raw_spin_lock_irqsave(&desc->lock) chain #2: __report_bad_irq() raw_spin_lock_irqsave(&desc->lock) for_each_action_of_desc() printk() spin_lock_irqsave(&port->lock); Fix this by changing the order of locks in serial8250_do_startup(): do disable_irq_nosync() first, which grabs desc->lock, and grab uart->port after that, so that chain #1 and chain #2 have same lock order.

Valmer Huhn	ce755e4eae	serial: 8250_exar: Fix number of ports for Commtech PCIe cards ... commit c6b9e95dde upstream. The following in 8250_exar.c line 589 is used to determine the number of ports for each Exar board: nr_ports = board->num_ports ? board->num_ports : pcidev->device & 0x0f; If the number of ports a card has is not explicitly specified, it defaults to the rightmost 4 bits of the PCI device ID. This is prone to error since not all PCI device IDs contain a number which corresponds to the number of ports that card provides. This particular case involves COMMTECH_4222PCIE, COMMTECH_4224PCIE and COMMTECH_4228PCIE cards with device IDs 0x0022, 0x0020 and 0x0021. Currently the multiport cards receive 2, 0 and 1 port instead of 2, 4 and 8 ports respectively. To fix this, each Commtech Fastcom PCIe card is given a struct where the number of ports is explicitly specified. This ensures 'board->num_ports' is used instead of the default 'pcidev->device & 0x0f'.

Lukas Wunner	e12f36220f	serial: pl011: Don't leak amba_ports entry on driver register error ... commit 89efbe70b2 upstream. pl011_probe() calls pl011_setup_port() to reserve an amba_ports[] entry, then calls pl011_register_port() to register the uart driver with the tty layer. If registration of the uart driver fails, the amba_ports[] entry is not released. If this happens 14 times (value of UART_NR macro), then all amba_ports[] entries will have been leaked and driver probing is no longer possible. (To be fair, that can only happen if the DeviceTree doesn't contain alias IDs since they cause the same entry to be used for a given port.) Fix it.

Lukas Wunner	eec2f7d9f0	serial: pl011: Fix oops on -EPROBE_DEFER ... commit 27afac93e3 upstream. If probing of a pl011 gets deferred until after free_initmem(), an oops ensues because pl011_console_match() is called which has been freed. Fix by removing the __init attribute from the function and those it calls. Commit 10879ae5f1 ("serial: pl011: add console matching function") introduced pl011_console_match() not just for early consoles but regular preferred consoles, such as those added by acpi_parse_spcr(). Regular consoles may be registered after free_initmem() for various reasons, one being deferred probing, another being dynamic enablement of serial ports using a DeviceTree overlay. Thus, pl011_console_match() must not be declared __init and the functions it calls mustn't either.

Tamseel Shams	8a0d860cbd	serial: samsung: Removes the IRQ not found warning ... commit 8c6c378b0c upstream. In few older Samsung SoCs like s3c2410, s3c2412 and s3c2440, UART IP is having 2 interrupt lines. However, in other SoCs like s3c6400, s5pv210, exynos5433, and exynos4210 UART is having only 1 interrupt line. Due to this, "platform_get_irq(platdev, 1)" call in the driver gives the following false-positive error: "IRQ index 1 not found" on newer SoC's. This patch adds the condition to check for Tx interrupt only for the those SoC's which have 2 interrupt lines.
