tracing: Remove size restriction on synthetic event cmd error logging
Currently, synthetic event command error strings are restricted to a length of MAX_FILTER_STR_VAL (256), which is too short for some commands already seen in the wild (with cmd strings longer than that showing up truncated in err_log). Remove the restriction so that no synthetic event command error string is ever truncated.

tracing: Fix tp_printk option related with tp_printk_stop_on_boot
The kernel parameter "tp_printk_stop_on_boot" starts with "tp_printk" which is
the same as another kernel parameter "tp_printk". If "tp_printk" setup is
called before the "tp_printk_stop_on_boot", it will override the latter
and keep it from being set.
This is similar to other kernel parameter issues, such as:

tracing: Don't inc err_log entry count if entry allocation fails

Doing it when it fails won't cause any problems other than wasting an

tracing: Propagate is_signed to expression
During expression parsing, a new expression field is created which
should inherit the properties of the operands, such as size and
is_signed.
is_signed propagation was missing, causing spurious errors with signed

tracing: Fix smatch warning for do while check in event_hist_trigger_parse()
The patch ec5ce0987541: "tracing: Allow whitespace to surround hist
trigger filter" from Jan 15, 2018, leads to the following Smatch
static checker warning:
kernel/trace/trace_events_hist.c:6199 event_hist_trigger_parse()
warn: 'p' can't be NULL.
Since p is always checked for a NULL value at the top of loop and
nothing in the rest of the loop will set it to NULL, the warning
is correct and might as well be 1 to silence the warning.

tracing: Fix smatch warning for null glob in event_hist_trigger_parse()
The recent rename of event_hist_trigger_parse() caused smatch
re-evaluation of trace_events_hist.c and as a result an old warning
was found:
kernel/trace/trace_events_hist.c:6174 event_hist_trigger_parse()
error: we previously assumed 'glob' could be null (see line 6166)
glob should never be null (and apparently smatch can also figure that
out and skip the warning when using the cross-function DB (but which
can't be used with a 0day build as it takes too much time to
generate)).
Nonetheless for clarity, remove the test but add a WARN_ON() in case
the code ever changes.

ftrace: Have architectures opt-in for mcount build time sorting
First S390 complained that the sorting of the mcount sections at build
time caused the kernel to crash on their architecture. Now PowerPC is
complaining about it too. And also ARM64 appears to be having issues.
It may be necessary to also update the relocation table for the values
in the mcount table. Not only do we have to sort the table, but also
update the relocations that may be applied to the items in the table.
If the system is not relocatable, then it is fine to sort, but if it is,
some architectures may have issues (although x86 does not as it shifts all
addresses the same).
Add a HAVE_BUILDTIME_MCOUNT_SORT that an architecture can set to say it is
safe to do the sorting at build time.
Also update the config to compile in build time sorting in the sorttable
code in scripts/ to depend on CONFIG_BUILDTIME_MCOUNT_SORT.

ftrace: Fix s390 breakage from sorting mcount tables
The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one. As the ftrace algorithm depends on it being sorted, bad things happen when it is not, and s390 experienced those bad things.

ftrace: Fix assuming build time sort works for s390
To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

sysctl: returns -EINVAL when a negative value is passed to proc_doulongvec_minmax
When we pass a negative value to the proc_doulongvec_minmax() function,
the function returns 0, but the corresponding interface value does not
change.
we can easily reproduce this problem with the following commands:
cd /proc/sys/fs/epoll
echo -1 > max_user_watches; echo $?; cat max_user_watches
This function requires a non-negative number to be passed in, so when a
negative number is passed in, -EINVAL is returned.

fs: move namespace sysctls and declare fs base directory
This moves the namespace sysctls to its own file as part of the kernel/sysctl.c spring cleaning Since we have now removed all sysctls for "fs", we now have to declare it on the filesystem code, we do that using the new helper, which reduces boiler plate code. We rename init_fs_shared_sysctls() to init_fs_sysctls() to reflect that now fs/sysctls.c is taking on the burden of being the first to register the base directory as well. Lastly, since init code will load in the order in which we link it we have to move the sysctl code to be linked in early, so that its early init routine runs prior to other fs code. This way, other filesystem code can register their own sysctls using the helpers after this: * register_sysctl_init() * register_sysctl() Link: https://lkml.kernel.org/r/20211129211943.640266-3-mcgrof@kernel.org Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Anil S Keshavamurthy <anil.s.keshavamurthy@intel.com> Cc: Antti Palosaari <crope@iki.fi> Cc: Christian Brauner <christian.brauner@ubuntu.com> Cc: "David S.

sysctl: add and use base directory declarer and registration helper
Patch series "sysctl: add and use base directory declarer and registration helper". In this patch series we start addressing base directories, and so we start with the "fs" sysctls. The end goal is we end up completely moving all "fs" sysctl knobs out from kernel/sysctl. This patch (of 6): Add a set of helpers which can be used to declare and register base directory sysctls on their own. We do this so we can later move each of the base sysctl directories like "fs", "kernel", etc, to their own respective files instead of shoving the declarations and registrations all on kernel/sysctl.c. The lazy approach has caught up and with this, we just end up extending the list of base directories / sysctls on one file and this makes maintenance difficult due to merge conflicts from many developers.

fs: move inode sysctls to its own file
Patch series "sysctl: 4th set of kernel/sysctl cleanups". This is slimming down the fs uses of kernel/sysctl.c to the point that the next step is to just get rid of the fs base directory for it and move that elsehwere, so that next patch series starts dealing with that to demo how we can end up cleaning up a full base directory from kernel/sysctl.c, one at a time. This patch (of 9): kernel/sysctl.c is a kitchen sink where everyone leaves their dirty dishes, this makes it very difficult to maintain. To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic. So move the inode sysctls to its own file. Since we are no longer using this outside of fs/ remove the extern declaration of its respective proc helper. We use early_initcall() as it is the earliest we can use.

firmware_loader: move firmware sysctl to its own files
Patch series "sysctl: 3rd set of kernel/sysctl cleanups", v2. This is the third set of patches to help address cleaning the kitchen seink in kernel/sysctl.c and to move sysctls away to where they are actually implemented / used. This patch (of 8): kernel/sysctl.c is a kitchen sink where everyone leaves their dirty dishes, this makes it very difficult to maintain. To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic. So move the firmware configuration sysctl table to the only place where it is used, and make it clear that if sysctls are disabled this is not used.

sysctl: use const for typically used max/min proc sysctls
When proc_dointvec_minmax() or proc_doulongvec_minmax() are used we are using the extra1 and extra2 parameters on the sysctl table only for a min and max boundary, these extra1 and extra2 arguments are then used for read-only operations. So make them const to reflect this.

watchdog: move watchdog sysctl interface to watchdog.c
The kernel/sysctl.c is a kitchen sink where everyone leaves their dirty dishes, this makes it very difficult to maintain. To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic of proc sysctl. So, move the watchdog syscl interface to watchdog.c. Use register_sysctl() to register the sysctl interface to avoid merge conflicts when different features modify sysctl.c at the same time.

sysctl: move some boundary constants from sysctl.c to sysctl_vals
sysctl has helpers which let us specify boundary values for a min or max int value. Since these are used for a boundary check only they don't change, so move these variables to sysctl_vals to avoid adding duplicate variables. This will help with our cleanup of kernel/sysctl.c.

Networking fixes for 5.17-rc1, including fixes from netfilter, bpf.
Current release - regressions:
- fix memory leaks in the skb free deferral scheme if upper layer
protocols are used, i.e. in-kernel TCP readers like TLS
Current release - new code bugs:
- nf_tables: fix NULL check typo in _clone() functions
- change the default to y for Vertexcom vendor Kconfig
- a couple of fixes to incorrect uses of ref tracking
- two fixes for constifying netdev->dev_addr
Previous releases - regressions:
- bpf:
- various verifier fixes mainly around register offset handling
when passed to helper functions
- fix mount source displayed for bpffs (none -> bpffs)
- bonding:
- fix extraction of ports for connection hash calculation
- fix bond_xmit_broadcast return value when some devices are down
- phy: marvell: add Marvell specific PHY loopback
- sch_api: don't skip qdisc attach on ingress, prevent ref leak
- htb: restore minimal packet size handling in rate control
- sfp: fix high power modules without diagnostic monitoring
- mscc: ocelot:
- don't let phylink re-enable TX PAUSE on the NPI port
- don't dereference NULL pointers with shared tc filters
- smsc95xx: correct reset handling for LAN9514
- cpsw: avoid alignment faults by taking NET_IP_ALIGN into account
- phy: micrel: use kszphy_suspend/_resume for irq aware devices,
avoid races with the interrupt
Previous releases - always broken:
- xdp: check prog type before updating BPF link
- smc: resolve various races around abnormal connection termination
- sit: allow encapsulated IPv6 traffic to be delivered locally
- axienet: fix init/reset handling, add missing barriers,
read the right status words, stop queues correctly
- add missing dev_put() in sock_timestamping_bind_phc()
Misc:
- ipv4: prevent accidentally passing RTO_ONLINK to
ip_route_output_key_hash() by sanitizing flags
- ipv4: avoid quadratic behavior in netns dismantle
- stmmac: dwmac-oxnas: add support for OX810SE
- fsl: xgmac_mdio: add workaround for erratum A-009885
