* license: fix and add SPDX license identifiers and drop license commentsThomas Haller2020-04-161-7/+0

This is not done manually, but by running the following script: --- #!/bin/bash # Tool to drop license comments, adding SPDX license identifiers, while preserving # copyright comments.

* lib: add const-ness to appropriate parameters in addr, attr, dataRohan Joyce2015-02-161-20/+20
| | | | | | | | | | | | | | | This patch changes the signatures of some functions to allow const pointers in places where a const qualified pointer is enough access for what the function does (e.g. nla_get_u8). It also changes some functions that take a pointer parameter and return a pointer derived from it to use the strchr idiom. This is not exhaustive in terms of places where const can be added, but it's a decent chunk that should not make the external api any more restrictive. http://lists.infradead.org/pipermail/libnl/2015-February/001826.html Signed-off-by: Rohan Joyce <rojoyce.github@gmail.com> Signed-off-by: Thomas Haller <thaller@redhat.com>

* nl_addr_parse handling of 'default', 'any', and 'all'Justin Mayfield2012-08-291-4/+3
| | | | | | | | | | | | I found a small bug in the nl_addr_parse function when being passed the strings "default", "any", or "all". Currently nl_addr_parse will create a zeroed nl_addr with a length corresponding to the family/hint or AF_INET if omitted. This behavior when used in conjunction with the libnl-route library to add default routes to the system has the side effect of creating a route to the host address 0.0.0.0/32. Attached is a patch that matches the iproute2 behavior more closely where we do set the family but the length of the nl_addr is set to 0.
* Fix types-related warnings based on clang diagnosticsКоренберг Марк2012-06-131-3/+3
| | | | | | | | | | | | | | | | | 1. Fix some places where unsigned value compared < 0 2. Fix obsolete %Z specifier to more portable %z 3. Some erroneous types substitution 4. nl_msec2str() - 64-bit msec is now properly used, Only safe changes. I mean int <--> uint32_t and signed/unsigned fixes. Some functinos require size_t argument instead of int, but changes of signatures of that functions is terrible thing. Also, I do not pretend for a full list of fixes. Just to shut up clang -Wall -Wextra One more thing. ifindex. I don't change that because changes will be too big for simple fix.

* Thread-safe error handlingThomas Graf2008-05-141-32/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order for the interface to become more thread safe, the error handling was revised to no longer depend on a static errno and error string buffer. This patch converts all error paths to return a libnl specific error code which can be translated to a error message using nl_geterror(int error). The functions nl_error() and nl_get_errno() are therefore obsolete. This change required various sets of function prototypes to be changed in order to return an error code, the most prominent are: struct nl_cache *foo_alloc_cache(...); changed to: int foo_alloc_cache(..., struct nl_cache **); struct nl_msg *foo_build_request(...); changed to: int foo_build_request(..., struct nl_msg **); struct foo *foo_parse(...); changed to: int foo_parse(..., struct foo **); This pretty much only leaves trivial allocation functions to still return a pointer object which can still return NULL to signal out of memory. This change is a serious API and ABI breaker, sorry!
