2018-10-02backports: genetlink: update completelyJohannes Berg
Replace all the different nested versions of generic netlink backport with a single one, covering from < 3.13 all the way to the upcoming netlink policy improvements in 4.20. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2018-10-02backports: fix genlmsg_nlhdr() backportJohannes Berg
Since 4.15 this no longer takes a family argument, so add that to the backports instead of trying to work around the family argument having changed type. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2018-02-23backport: update genl_dump_check_consistent() backportLuca Coelho
The genl_dump_check_consistent() function was changed in v4.15 to use only two arguments. The family is not needed anymore, because we were erroneously subtracting the header size and that was fixed in v4.15. Since the family was only used to check the header size, we can create a dummy with hdrsize = 0, which will allow us to call the old version of the function. There is a good side-effect to doing this: the bug is going to be fixed, because with hdrsize = 0 we will not subtract anything and it will have the same effect as the fix.

2017-10-24backports: fix the extack backportJohannes Berg
I neglected to take into account that the spatch will also be applied to the backport-4.12.c file itself, fix that. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2017-10-17backports: fully add netlink extack for generic netlinkJohannes Berg
The previous backport just made the code compatible, but removed the extack functionality entirely. By ignoring the setsockopt() and just assuming that userspace does in fact support extack (which is true for all of wifi and in fact all users of libnl), we can support full extack functionality even on kernels that don't support it.

2017-02-09backports: don't use __ro_after_init with genl families on <=4.9Johannes Berg
4.9 introduced __ro_after_init, but generic netlink family registration was only changed to allow it in 4.10, otherwise deregistration will crash due to writing to the RO memory. Unfortunately, spatch doesn't handle this, so manually patch the families to replace __ro_after_init with __genl_ro_after_init which is defined to nothing on kernel version <= 4.9.

2017-02-06backports: add backport for genl_family_attrbuf() functionArend van Spriel
The function genl_family_attrbuf() was added to the kernel. This backport caries the warning for parallel ops, but it does not assert the genl_mutex as it does not have access to it.

2016-07-08backports: genetlink: add define for GENL_UNS_ADMIN_PERMArend van Spriel
Since commit 5ed071ec9992 ("nl80211: Allow privileged operations from user namespaces") the definition GENL_UNS_ADMIN_PERM is used by nl80211.c. Add definition mapping to GENL_ADMIN_PERM for kernel not having it thus reverting to previous permission check.

2015-12-06header: fix genl_notify() on kernel 4.4Hauke Mehrtens
The change of the parameters of genl_notify() is in kernel 4.4. This backport should not be applied for kernel 4.4 and newer kernel versions. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>

I recently changed the generic netlink registration and multicast group APIs to be safer. Backport these changes by implementing all the new APIs in terms of what was in the kernel before. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
