parser: remove unnecessary strlen()

2009-12-15T16:53:33Z

No functional change. Cache strlen() result to avoid recalculating it up to 3 times on the worst case. Reduces code size a little by 32 bytes: text data bss dec hex filename 1385 0 0 1385 569 lib/parser.o-BEFORE 1353 0 0 1353 549 lib/parser.o-AFTER Signed-off-by: André Goddard Rosa Cc: Randy Dunlap Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

vfs: Use const for kernel parser table

2008-10-13T17:10:37Z

This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble. This was posted for review some time ago and I believe its been in -mm since then. Signed-off-by: Steven Whitehouse Cc: Alexander Viro Signed-off-by: Linus Torvalds

add match_strlcpy() us it to make v9fs make uname and remotename parsing more robust

2008-05-15T00:23:25Z

match_strcpy() is a somewhat creepy function: the caller needs to make sure that the destination buffer is big enough, and when he screws up or forgets, match_strcpy() happily overruns the buffer. There's exactly one customer: v9fs_parse_options(). I believe it currently can't overflow its buffer, but that's not exactly obvious. The source string is a substing of the mount options. The kernel silently truncates those to PAGE_SIZE bytes, including the terminating zero. See compat_sys_mount() and do_mount(). The destination buffer is obtained from __getname(), which allocates from name_cachep, which is initialized by vfs_caches_init() for size PATH_MAX. We're safe as long as PATH_MAX <= PAGE_SIZE. PATH_MAX is 4096. As far as I know, the smallest PAGE_SIZE is also 4096. Here's a patch that makes the code a bit more obviously correct. It doesn't depend on PATH_MAX <= PAGE_SIZE.

[AFS]: Make the match_*() functions take const options.

2007-05-03T10:10:39Z

Make the match_*() functions take a const pointer to the options table and make strings pointers in the options table const too. Signed-off-by: David Howells Signed-off-by: David S. Miller

Linux-2.6.12-rc2

2005-04-16T22:20:36Z

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!
