[PATCH] shmdt cannot detach not-alined shm segment cleanly.

2006-03-01T22:36:31+00:00

sys_shmdt() can manage shm segments which are covered by multiple vmas. (This can happen when a user uses mprotect() after shmat().) This works well if shm is aligned to PAGE_SIZE, but if not, the last segment cannot be detached. It is because a comparison in sys_shmdt() (vma->vm_end - addr) < size addr == return address of shmat() size == shmsize, argments to shmget() size should be aligned to PAGE_SIZE before being compared with vma->vm_end, which is aligned.

[PATCH] SHM_NORESERVE flags for shmget()

2005-11-07T15:53:37+00:00

Add SHM_NORESERVE functionality similar to MAP_NORESERVE for shared memory segments. This is mainly to avoid abuse of OVERCOMMIT_ALWAYS and this flag is ignored for OVERCOMMIT_NEVER. Signed-off-by: Badari Pulavarty Cc: Hugh Dickins Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] hugetlb: remove repeated code

2005-10-30T04:40:43+00:00

Clean up some repeated code related to HugeTLB. hugetlb_zero_setup would have already allocated the file->f_op. Signed-off-by: Krishnakumar. R Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ipc: convert /proc/sysvipc/* to generic seq_file interface

2005-09-07T23:57:26+00:00

Change the /proc/sysvipc/shm|sem|msg files to use the generic seq_file implementation for struct ipc_ids. Signed-off-by: Mike Waychison Cc: Manfred Spraul Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] shm: CONFIG_SHMEM=n build fix

2005-08-02T04:38:00+00:00

Fix bug found by Grant Coady 's autobuild setup. shmem_set_policy() and shmem_get_policy() are macros if !CONFIG_SHMEM, so this doesn't work. 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!
