[PATCH] Rework of IPC auditing

2006-05-01T10:10:04+00:00

1) The audit_ipc_perms() function has been split into two different functions: - audit_ipc_obj() - audit_ipc_set_perm() There's a key shift here... The audit_ipc_obj() collects the uid, gid, mode, and SElinux context label of the current ipc object. This audit_ipc_obj() hook is now found in several places. Most notably, it is hooked in ipcperms(), which is called in various places around the ipc code permforming a MAC check. Additionally there are several places where *checkid() is used to validate that an operation is being performed on a valid object while not necessarily having a nearby ipcperms() call. In these locations, audit_ipc_obj() is called to ensure that the information is captured by the audit system. The audit_set_new_perm() function is called any time the permissions on the ipc object changes. In this case, the NEW permissions are recorded (and note that an audit_ipc_obj() call exists just a few lines before each instance). 2) Support for an AUDIT_IPC_SET_PERM audit message type. This allows for separate auxiliary audit records for normal operations on an IPC object and permissions changes. Note that the same struct audit_aux_data_ipcctl is used and populated, however there are separate audit_log_format statements based on the type of the message. Finally, the AUDIT_IPC block of code in audit_free_aux() was extended to handle aux messages of this new type. No more mem leaks I hope ;-) Signed-off-by: Al Viro

[PATCH] IPC: access to unmapped vmalloc area in grow_ary()

2006-04-18T01:40:40+00:00

grow_ary() should not copy struct ipc_id_ary (it copies new->p, not new). Due to this, memcpy() src pointer could hit unmapped vmalloc page when near page boundary. Found during OpenVZ stress testing Signed-off-by: Alexey Kuznetsov Signed-off-by: Kirill Korotaev Signed-off-by: Linus Torvalds

BUG_ON() Conversion in ipc/util.c

2006-03-31T23:20:23+00:00

this changes if() BUG(); constructs to BUG_ON() which is cleaner, contains unlikely() and can better optimized away. Signed-off-by: Eric Sesterhenn Signed-off-by: Adrian Bunk

[PATCH] sem2mutex: ipc, id.sem

2006-03-26T16:56:55+00:00

Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well. Signed-off-by: Ingo Molnar Cc: Manfred Spraul Signed-off-by: Lee Schermerhorn Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

correct email address of Manfred Spraul

2006-01-15T01:43:54+00:00

I tried to send the forcedeth maintainer an email, but it came back with: "The mail address manfreds@colorfullife.com is not read anymore. Please resent your mail to manfred@ instead of manfreds@." This patch fixes this. Signed-off-by: Adrian Bunk

[PATCH] move capable() to capability.h

2006-01-12T02:42:13+00:00

- Move capable() from sched.h to capability.h; - Use where capable() is used (in include/, block/, ipc/, kernel/, a few drivers/, mm/, security/, & sound/; many more drivers/ to go) Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] more kernel-doc cleanups, additions

2005-11-07T15:53:55+00:00

Various core kernel-doc cleanups: - add missing function parameters in ipc, irq/manage, kernel/sys, kernel/sysctl, and mm/slab; - move description to just above function for kernel_restart() Signed-off-by: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ipc: add generic struct ipc_ids seq_file iteration

2005-09-07T23:57:25+00:00

The following two patches convert /proc/sysvipc/* to use seq_file. This gives us the following: - Self-consistent IPC records in proc. - O(n) reading of the files themselves. This patch: Add a generic method for ipc types to be displayed using seq_file. This patch abstracts out seq_file iterating over struct ipc_ids into ipc/util.c Signed-off-by: Mike Waychison Cc: Manfred Spraul Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
