`tools/perf/util/map.c` has a function named `maps__insert` that acquires a write lock if its in multithread context. Even though this lock is released when function successfully completes, there's a branch that is executed when `maps_by_name == NULL` that returns from this function without releasing the write lock. Added an `up_write` to release the lock when this happens. Fixes: a7c2b572 ("perf map_groups: Auto sort maps by name, if needed") Signed-off-by:

Kernel commit 88903c46 ("tracing/probe: Add ustring type for user-space string") adds support for user-space strings when type 'ustring' is specified. Here is an example using sysfs command line interface for kprobes: Function to probe: struct filename * getname_flags(const char __user *filename, int flags, int *empty) Setup: # cd /sys/kernel/debug/tracing/ # echo 'p:tmr1 getname_flags +0(%r2):ustring' > kprobe_events # cat events/kprobes/tmr1/format | fgrep print print fmt: "(%lx) arg1=\"%s\"", REC->__probe_ip, REC->arg1 # echo 1 > events/kprobes/tmr1/enable # touch /tmp/111 # echo 0 > events/kprobes/tmr1/enable # cat trace|fgrep /tmp/111 touch-5846 [005] d..2 255520.717960: tmr1:\ (getname_flags+0x0/0x400) arg1="/tmp/111" Doing the same with the perf tool fails. Using type 'string' succeeds: # perf probe "vfs_getname=getname_flags:72 pathname=filename:string" Added new event: probe:vfs_getname (on getname_flags:72 with pathname=filename:string) .... # perf probe -d probe:vfs_getname Removed event: probe:vfs_getname However using type 'ustring' fails (output before): # perf probe "vfs_getname=getname_flags:72 pathname=filename:ustring" Failed to write event: Invalid argument Error: Failed to add events. # Fix this by adding type 'ustring' in function convert_variable_type(). Using ustring succeeds (output after): # ./perf probe "vfs_getname=getname_flags:72 pathname=filename:ustring" Added new event: probe:vfs_getname (on getname_flags:72 with pathname=filename:ustring) You can now use it in all perf tools, such as: perf record -e probe:vfs_getname -aR sleep 1 # Note: This issue also exists on x86, it is not s390 specific.

Commit a2408a70 ("perf evlist: Maintain evlist->all_cpus") introduces a test case for cpumap merge operation, see functions perf_cpu_map__merge() and test__cpu_map_merge(). The test case fails on s390 with this error message: [root@m35lp76 perf]# ./perf test -Fvvvvv 52 52: Merge cpu map : --- start --- cpumask list: 1-2,4-5,7 perf: /root/linux/tools/include/linux/refcount.h:131:\ refcount_sub_and_test: Assertion `!(new > val)' failed. Aborted (core dumped) [root@m35lp76 perf]# The root cause is in the function test__cpu_map_merge(): It creates two cpu_maps named 'a' and 'b': struct perf_cpu_map *a = perf_cpu_map__new("4,2,1"); struct perf_cpu_map *b = perf_cpu_map__new("4,5,7"); and creates a third map named 'c' which is the result of the merge of maps a and b: struct perf_cpu_map *c = perf_cpu_map__merge(a, b); After some verifaction of the merged cpu_map all three of them are have their reference count reduced and are freed: perf_cpu_map__put(a); (1) perf_cpu_map__put(b); perf_cpu_map__put(c); The release of perf_cpu_map__put(a) is wrong. The map is already released and free'ed as part of the function perf_cpu_map__merge(struct perf_cpu_map *orig, | struct perf_cpu_map *other) +--> perf_cpu_map__put(orig); | +--> cpu_map__delete(orig) At the end perf_cpu_map_put() is called for map 'orig' alias 'a' and since the reference count is 1, the map is deleted, as can be seen by the following gdb trace: (gdb) where #0 tcache_put (tc_idx=0, chunk=0x156cc30) at malloc.c:2940 #1 _int_free (av=0x3fffd49ee80 <main_arena>, p=0x156cc30, have_lock=<optimized out>) at malloc.c:4222 #2 0x00000000012d5e78 in cpu_map__delete (map=0x156cc40) at cpumap.c:31 #3 0x00000000012d5f7a in perf_cpu_map__put (map=0x156cc40) at cpumap.c:45 #4 0x00000000012d723a in perf_cpu_map__merge (orig=0x156cc40, other=0x156cc60) at cpumap.c:343 #5 0x000000000110cdd0 in test__cpu_map_merge ( test=0x14ea6c8 <generic_tests+2856>, subtest=-1) at tests/cpumap.c:128 Thus the perf_cpu_map__put(a) (see (1) above) frees map 'a' a second time and causes the failure. Fix this be removing that function call. Output after: [root@m35lp76 perf]# ./perf test -Fvvvvv 52 52: Merge cpu map : --- start --- cpumask list: 1-2,4-5,7 ---- end ---- Merge cpu map: Ok [root@m35lp76 perf]# Signed-off-by:

perf with CoreSight fails to record trace data with command: perf record -e cs_etm/@tmc_etr0/u --per-thread ls failed to set sink "" on event cs_etm/@tmc_etr0/u with 21 (Is a directory)/perf/ This failure is root caused with the commit 1dc92556 ("perf parse: Add a deep delete for parse event terms"). The log shows, cs_etm fails to parse the sink attribution; cs_etm event relies on the event configuration to pass sink name, but the event specific configuration data cannot be passed properly with flow: get_config_terms() ADD_CONFIG_TERM(DRV_CFG, term->val.str); __t->val.str = term->val.str; `> __t->val.str is assigned to term->val.str; parse_events_terms__purge() parse_events_term__delete() zfree(&term->val.str); `> term->val.str is freed and assigned to NULL pointer; cs_etm_set_sink_attr() sink = __t->val.str; `> sink string has been freed. To fix this issue, in the function get_config_terms(), this patch changes to use strdup() for allocation a new duplicate string rather than directly assignment string pointer. This patch addes a new field 'free_str' in the data structure perf_evsel_config_term; 'free_str' is set to true when the union is used as a string pointer; thus it can tell perf_evsel__free_config_terms() to free the string.

The struct perf_evsel_config_term::val is a union which contains fields 'callgraph', 'drv_cfg' and 'branch' as string pointers. This leads to the complex code logic for handling every type's string separately, and it's hard to release string as a general way. This patch refactors the structure to add a common field 'str' in the 'val' union as string pointer and remove the other three fields 'callgraph', 'drv_cfg' and 'branch'. Without passing field name, the patch simplifies the string handling with macro ADD_CONFIG_TERM_STR() for string pointer assignment. This patch fixes multiple warnings of line over 80 characters detected by checkpatch tool. Signed-off-by:

Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity Pull IMA updates from Mimi Zohar: "Two new features - measuring certificates and querying IMA for a file hash - and three bug fixes: - Measuring certificates is like the rest of IMA, based on policy, but requires loading a custom policy. Certificates loaded onto a keyring, for example during early boot, before a custom policy has been loaded, are queued and only processed after loading the custom policy. - IMA calculates and caches files hashes. Other kernel subsystems, and possibly kernel modules, are interested in accessing these cached file hashes. The bug fixes prevent classifying a file short read (e.g. shutdown) as an invalid file signature, add a missing blank when displaying the securityfs policy rules containing LSM labels, and, lastly, fix the handling of the IMA policy information for unknown LSM labels" * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: IMA: Defined delayed workqueue to free the queued keys IMA: Call workqueue functions to measure queued keys IMA: Define workqueue for early boot key measurements IMA: pre-allocate buffer to hold keyrings string ima: ima/lsm policy rule loading logic bug fixes ima: add the ability to query the cached hash of a given file ima: Add a space after printing LSM rules for readability IMA: fix measuring asymmetric keys Kconfig IMA: Read keyrings= option from the IMA policy IMA: Add support to limit measuring keys KEYS: Call the IMA hook to measure keys IMA: Define an IMA hook to measure keys IMA: Add KEY_CHECK func to measure keys IMA: Check IMA policy flag ima: avoid appraise error for hash calc interrupt

cgroup events are always installed in the cpuctx. However, when it is not installed via IPI, list_update_cgroup_event() adds it to cpuctx of current CPU, which triggers list corruption: [] list_add double add: new=ffff888ff7cf0db0, prev=ffff888ff7ce82f0, next=ffff888ff7cf0db0. To reproduce this, we can simply run: # perf stat -e cs -a & # perf stat -e cs -G anycgroup Fix this by installing it to cpuctx that contains event->ctx, and the proper cgrp_cpuctx_list.

Decreasing sysctl_perf_event_mlock between two consecutive perf_mmap()s of a perf ring buffer may lead to an integer underflow in locked memory accounting. This may lead to the undesired behaviors, such as failures in BPF map creation. Address this by adjusting the accounting logic to take into account the possibility that the amount of already locked memory may exceed the current limit. Fixes: c4b75479 ("perf/core: Make the mlock accounting simple again") Suggested-by:
