2021-07-01kernel.h: split out kstrtox() and simple_strtox() to a separate headerAndy Shevchenko1-0/+1
kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out kstrtox() and simple_strtox() helpers. At the same time convert users in header and lib folders to use new header. Though for time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

2021-05-06lib: parser: clean up kernel-docRandy Dunlap1-23/+38
Mark match_uint() as kernel-doc notation since it is already fully annotated as such. Use % prefix on constants in kernel-doc comments. Convert function return descriptions to use the "Return:" kernel-doc notation.

match_wildcard function is a simple implementation of wildcard matching algorithm. It only supports two usual wildcardes: '*' - matches zero or more characters '?' - matches one character This algorithm is safe since it is non-recursive.

2012-10-06lib/parser.c: avoid overflow in match_number()Alex Elder1-2/+8
The result of converting an integer value to another signed integer type that's unable to represent the original value is implementation defined. (See notes in section 6.3.1.3 of the C standard.) In match_number(), the result of simple_strtol() (which returns type long) is assigned to a value of type int. Instead, handle the result of simple_strtol() in a well-defined way, and return -ERANGE if the result won't fit in the int variable used to hold the parsed result. No current callers pay attention to the particular error value returned, so this additional return code shouldn't do any harm.

2008-10-13vfs: Use const for kernel parser tableSteven Whitehouse1-1/+1
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.

2008-05-14add match_strlcpy() us it to make v9fs make uname and remotename parsing ↵Markus Armbruster1-12/+20
more robust 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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+220
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!
