* include: use <linux/$file> instead of <linux-private/linux/$file>Thomas Haller2023-08-083-3/+3
| | | | | | As we now copy all linux headers, and we have include/linux-private in our include search path, just include the linux headers as we commonly do.
* include: include private linux headers with explicit pathThomas Haller2023-08-033-3/+3
| | | | | | | We have copies of the linux headers in include/linux-private. For those files, include the copies explicitly. No practice there is no difference, since we build with :-Ilinux-private".

* include: split and drop "netlink-private/types.h"Thomas Haller2023-08-025-3/+86
| | | | | Move all the declarations from "netlink-private/types.h" to places closer to where they are used.
* lib: use _nl_{init,exit} instead of __{init,exit}Thomas Haller2023-07-281-2/+2
| | | | | We should have things with "nl" prefix in our headers. Also, netlink-private/netlink.h is not header-only, preferably header-only stuff is in netlink-private/utils.h
* all: use "_nl_packed" macro instead of "__attribute__((packed))"Thomas Haller2023-07-281-1/+1

* all: rework ATTR_DIFF() macros to not generate attribute namesThomas Haller2023-07-281-23/+38
| | | | | | | | | | I find macros that stitch together names like "FAMILY_ATTR_##ATTR" very confusing, because we no longer see where a certain name is used. It breaks grepping for symbols, and it breaks cscope. Yes, it's more verbose to not do that. If you really think that those names are too verbose, then maybe they should get a shorter name. And not use macros to make them palatable.
* lib: make nl_object_clone() out-of-memory safeThomas Haller2022-03-162-1/+4
| | | | | | | | | | | | | | | | | nl_object_clone() first does a shallow copy using memcpy(). That is useful, because it can correctly copy simple fields (like numbers). For pointer values, we need to implement oo_clone() to fixup the pointers and get the deep-copy correct. Now, oo_clone() must always follow through, to un-alias the copied pointer. In particular also in the error case. The oo_clone() implementations sometimes fail (with ENOMEM) and just return. In those cases, we must make sure that we don't leave the wrong pointers there. The pointers must be cleared first. Otherwise, any failure (which basically are ENOMEM) leave the object in an inconsistent state, and we double-free/use-after-free the pointers.
* license: fix and add SPDX license identifiers and drop license commentsThomas Haller2020-04-165-35/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This also fixes a few wrong SPDX license identifiers, where the original license comment indicates GPL-2.0-only. 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: update ce-mask to uint64_tDavid Ahern2016-02-123-7/+7
| | | | | | | | | | | | | | | | | | | | lib/route/link.c already defines 32 attributes which fills the current uint32_t used for ce_mask. To accommodate more attributes the mask needs to be expanded. This patch updates the definition to uint64_t. The nl_object_diff API is maintained for ABI with existing users. A new nl_object_diff64 API is added for the expanded attribute list. The MSB of the 32-bit API is used to indicate if higher order attributes had a mismatch. (Suggested by Thomas). Note that LINK_ATTR_LINK_NETNSID changes. But since the attribute flags are not public API it shouldn't be a problem. http://lists.infradead.org/pipermail/libnl/2015-December/002078.html http://lists.infradead.org/pipermail/libnl/2015-December/002083.html Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: Thomas Haller <thaller@redhat.com>

| | | | | | | | | | | | | | | | | | The return value of the *nl_send_simple() functions is inconsistent and not according to the documentation. nl_send_simple() is document to return the number of bytes sent.

See also commit b70174668b9867de573cf51471bc98bfe7fd2bc3 which changed behavior of nl_rtgen_request() to be according to documenation.

* idiag: fix idiagnl_exts2str()Thomas Haller2014-11-251-9/+20
| | | | | | | | | | | | | | | | | | idiagnl_exts2str() is used to print req->idiag_ext, which is the extention types combined as flags, such as ( (1 << (INET_DIAG_TOS - 1)) | (1 << (INET_DIAG_MEMINFO - 1)) ). This function was wrong from the beginning because the string lookup array had indexes such as 'INET_DIAG_TOS', instead of '(1 << (INET_DIAG_TOS - 1)'. Fix also idiagnl_attrs2str() which now converts an extension type (e.g. INET_DIAG_TOS) to a string. Still this function is deprecated, as the function name is not clear and it is not used or very useful.

Also deprecated idiagnl_attrs2str() because there is already idiagnl_exts2str(). idiagnl_attrs2str() in the sense of libnl change flags (ce_mask) makes no sense.

| | | | | | | | | | | | | | | | | | | | When we test idiag on 3.4 kernel, we always get ERANGE. This is because libnl has its own copy for SK_MEMINFO_*, which is actually newer than 3.4, where SK_MEMINFO_VARS is larger than kernel's. We add a copy from latest kernel, so on older kernel libnl should still compile. Note, for kernel < 3.6 we don't have SK_MEMINFO_BACKLOG, we have to relax the minlen. 'sock_diag.h' comes from v3.17 kernel sources (bfe01a5ba2490f299e1d2d5508cbbbadd897bbe9), file 'include/uapi/linux/sock_diag.h'.

- Inet diag allows users to gather low-level socket information. - This library provides a higher-level API for creating inetdiag requests (via idiagnl_connect and idiagnl_send_simple) and parsing the replies (via idiagnl_msg_parse). A cache is also provided (via idiagnl_msg_alloc_cache). - Request and message objects provide APIs for accessing and setting the various properties of each. - This library also allows the user to parse the inetdiag response attributes which contain information about traffic class, TOS, congestion, socket memory info, and more depending on the kernel version used. - Includes doxygen documentation.
