Some distributions, such as centos stream 9, still have a version of coreutils which does not yet support the %Hr and %Lr formats for stat(1) [1, 2]. Running ublk selftests on these distributions results in the following error in tests that use the _get_disk_dev_t helper: line 23: ?r: syntax error: operand expected (error token is "?r") To better accommodate older distributions, rewrite _get_disk_dev_t to use the much older %t and %T formats for stat instead.

6 daysselftests: mptcp: diag: use mptcp_lib_get_info_valueGeliang Tang1-3/+2
When running diag.sh in a loop, chk_dump_one will report the following "grep: write error": 13 ....chk 2 cestab [ OK ] grep: write error 14 ....chk dump_one [ OK ] 15 ....chk 2->0 msk in use after flush [ OK ] 16 ....chk 2->0 cestab after flush [ OK ] This error is caused by a broken pipe. When the output of 'ss' is processed by grep, 'head -n 1' will exit immediately after getting the first line, causing the subsequent pipe to close. At this time, if 'grep' is still trying to write data to the closed pipe, it will trigger a SIGPIPE signal, causing a write error. One solution is not to use this problematic "head -n 1" command, but to use mptcp_lib_get_info_value() helper defined in mptcp_lib.sh to get the value of 'token'.

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Initialize hash variables in ftrace subops logic The fix that simplified the ftrace subops logic opened a path where some variables could be used without being initialized, and done subtly where the compiler did not catch it. Initialize those variables to the EMPTY_HASH, which is the default hash. - Reinitialize the hash pointers after they are freed Some of the hash pointers in the subop logic were freed but may still be referenced later. To prevent use-after-free bugs, initialize them back to the EMPTY_HASH. - Free the ftrace hashes when they are replaced The fix that simplified the subops logic updated some hash pointers, but left the original hash that they were pointing to where they are no longer used. This caused a memory leak. Free the hashes that are pointed to by the pointers when they are replaced. - Fix size initialization of ftrace direct function hash The ftrace direct function hash used by BPF initialized the hash size incorrectly. It checked the size of items to a hard coded 32, which made the hash bit size of 5. The hash size is supposed to be limited by the bit size of the hash, as the bitmask is allowed to be greater than 5. Rework the size check to first pass the number of elements to fls() and then compare that to FTRACE_HASH_MAX_BITS before allocating the hash. - Fix format output of ftrace_graph_ent_entry event The field depth of the ftrace_graph_ent_entry event is of size 4 but the output showed it as unsigned long and use "%lu". Change it to unsigned int and use "%u" in the print format that is displayed to user space. - Fix the trace event filter on strings Events can be filtered on numbers or string values. The return value checked from strncpy_from_kernel_nofault() and strncpy_from_user_nofault() was used to determine if reading the strings would fault or not. It would return fault if the value was non zero, which is basically meant that it was always considering the read as a fault. - Add selftest to test trace event string filtering In order to catch the breakage of the string filtering, add a self test to make sure that it continues to work. * tag 'trace-v6.15-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: selftests: Add testing a user string to filters tracing: Fix filter string testing ftrace: Fix type of ftrace_graph_ent_entry.depth ftrace: fix incorrect hash size in register_ftrace_direct() ftrace: Free ftrace hashes after they are replaced in the subops code ftrace: Reinitialize hash to EMPTY_HASH after freeing ftrace: Initialize variables for ftrace_startup/shutdown_subops()

Testing revealed the following error message for a CXL memdev that has Feature support: [ 56.690430] cxl mem0: Resources present before probing Attach the allocation of cxl_fwctl to the parent device of cxl_memdev. devm_add_* calls for cxl_memdev should not happen before the memdev probe function or outside the scope of the memdev driver. cxl_test missed this bug because cxl_test always arranges for the cxl_mem driver to be loaded before cxl_mock_mem runs.

13 daystools: ynl-gen: individually free previous values on double setJakub Kicinski1-17/+45
When user calls request_attrA_set() multiple times (for the same attribute), and attrA is of type which allocates memory - we try to free the previously associated values. For array types (including multi-attr) we have only freed the array, but the array may have contained pointers. Refactor the code generation for free attr and reuse the generated lines in setters to flush out the previous state. Since setters are static inlines in the header we need to add forward declarations for the free helpers of pure nested structs. Track which types get used by arrays and include the right forwad declarations. At least ethtool string set and bit set would not be freed without this. Tho, admittedly, overriding already set attribute twice is likely a very very rare thing to do.

14 daysselftests/ftrace: Differentiate bash and dash in dynevent_limitations.tcSteven Rostedt1-1/+22
bash and dash evaluate variables differently. dash will evaluate '\\' every time it is read whereas bash does not. TEST_STRING="$TEST_STRING \\$i" echo $TEST_STRING With i=123 On bash, that will print "\123" but on dash, that will print the escape sequence of \123 as the \ will be interpreted again in the echo. The dynevent_limitations.tc test created a very large list of arguments to test the maximum number of arguments to pass to the dynamic events file. It had a loop of: TEST_STRING=$1 # Acceptable for i in `seq 1 $MAX_ARGS`; do TEST_STRING="$TEST_STRING \\$i" done echo "$TEST_STRING" >> dynamic_events This worked fine on bash, but when run on dash it failed. This was due to dash interpreting the "\\$i" twice. Once when it was assigned to TEST_STRING and a second time with the echo $TEST_STRING. bash does not process the backslash more than the first time. To solve this, assign a double backslash to a variable "bs" and then echo it to "ts". If "ts" changes, it is dash, if not, it is bash. Then update "bs" accordingly, and use that to assign TEST_STRING. Now this could possibly just check if "$BASH" is defined or not, but this is testing if the issue exists and not just which shell is being used.
