Generate a REPORTED LUNS DATA HAS CHANGED Unit Attention if sysfs "max_luns" is used to change the number of scsi_debug LUNs. This is only done if scsi_debug_scsi_level is SPC-3 or above. Additionally, implement SPC-4 behavior which only generates this Unit Attention on the first LUN on the target to receive a command after the change. This condition is cleared when a REPORT LUNS command is received. Signed-off-by: Ewan D.

Commit e05fe292 (qla2xxx: Honor FCP_RSP retry delay timer field.) causes systems to busy-wait for about 3 minutes after boot prior to detecting SAN disks. During this wait period one kworker is running full-time (though /proc/<pid>/stack has no useful data). Another kworker is waiting for IO to complete during that whole time period. Looking at drivers/scsi/qla2xxx/qla_os.c, fcport->retry_delay_timestamp has a special value of 0 though that 0 value forces system to wait when jiffies is very large value (e.g. 4294952605 - "negative" value when signed on 32bit systems).

Commit a074335a ("x86, um: Mark system call tables readonly") was supposed to mark the sys_call_table in UML as RO by adding the const, but it doesn't have the desired effect as it's nevertheless being placed into the data section since __cacheline_aligned enforces sys_call_table being placed into .data..cacheline_aligned instead. We need to use the ____cacheline_aligned version instead to fix this issue. Before: $ nm -v arch/x86/um/sys_call_table_64.o | grep -1 "sys_call_table" U sys_writev 0000000000000000 D sys_call_table 0000000000000000 D syscall_table_size After: $ nm -v arch/x86/um/sys_call_table_64.o | grep -1 "sys_call_table" U sys_writev 0000000000000000 R sys_call_table 0000000000000000 D syscall_table_size Fixes: a074335a ("x86, um: Mark system call tables readonly") Cc: H.

futex_atomic_cmpxchg_inatomic() does not work on UML because it triggers a copy_from_user() in kernel context. On UML copy_from_user() can only be used if the kernel was called by a real user space process such that UML can use ptrace() to fetch the value.

Pull audit fix from Paul Moore: "One audit patch to resolve a panic/oops when recording filenames in the audit log, see the mail archive link below. The fix isn't as nice as I would like, as it involves an allocate/copy of the filename, but it solves the problem and the overhead should only affect users who have configured audit rules involving file names.

This reverts commit 24a0aa21. It's causing severe userspace breakage. Namely, all the utilities from wireless-utils which are relying on CONFIG_WEXT (which means tools like 'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw' utility in newer wireless-tools, which is supposed to be a replacement for all the "deprecated" binaries, but it's far away from being massively adopted. Please see [1] for example of the userspace breakage this is causing. In addition to that, Larry Finger reports [2] that this patch is also causing ipw2200 driver being impossible to build. To me this clearly shows that CONFIG_WEXT is far, far away from being "deprecated enough" to be removed.

Commit ac61d195 (scsi: set correct completion code in scsi_send_eh_cmnd()) introduced a bug. It changed the stored return value from a queuecommand call, but it didn't take into account that the return value was used again later on. This patch fixes the bug by changing the later usage. There is a big comment in the middle of scsi_send_eh_cmnd() which does a good job of explaining how the routine works. But it mentions a "rtn = FAILURE" value that doesn't exist in the code. This patch adjusts the code to match the comment (I assume the comment is right and the code is wrong). This fixes Bugzilla #88341.
