File 0023-compat-genetlink-remove-userhdr-from-struct-genl_inf.patch of Package drbd
From 1412792a443ddc696fd1c8981a6cc544272f54bf Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Moritz=20WanzenBug=20Wanzenb=C3=B6ck?= <moritz.wanzenboeck@linbit.com> Date: Wed, 13 Sep 2023 15:46:12 +0200 Subject: [PATCH] compat: genetlink: remove userhdr from struct genl_info See also upstream Linux kernel commit bffcc6882a1b ("genetlink: remove userhdr from struct genl_info") Original message: Only three families use info->userhdr today and going forward we discourage using fixed headers in new families. So having the pointer to user header in struct genl_info is an overkill. Compute the header pointer at runtime. --- .../cocci/genl_info_userhdr__no_present.cocci | 5 +++++ drbd/drbd-kernel-compat/gen_patch_names.c | 3 +++ drbd/drbd-kernel-compat/tests/have_genl_info_userhdr.c | 7 +++++++ drbd/drbd_nl.c | 6 +++--- 4 files changed, 18 insertions(+), 3 deletions(-) create mode 100644 drbd/drbd-kernel-compat/cocci/genl_info_userhdr__no_present.cocci create mode 100644 drbd/drbd-kernel-compat/tests/have_genl_info_userhdr.c diff --git a/drbd/drbd-kernel-compat/cocci/genl_info_userhdr__no_present.cocci b/drbd/drbd-kernel-compat/cocci/genl_info_userhdr__no_present.cocci new file mode 100644 index 000000000000..75e787797068 --- /dev/null +++ b/drbd/drbd-kernel-compat/cocci/genl_info_userhdr__no_present.cocci @@ -0,0 +1,5 @@ +@@ +expression info; +@@ +- genl_info_userhdr(info) ++ info->userhdr diff --git a/drbd/drbd-kernel-compat/gen_patch_names.c b/drbd/drbd-kernel-compat/gen_patch_names.c index e4a65a3c451e..b136acf3148a 100644 --- a/drbd/drbd-kernel-compat/gen_patch_names.c +++ b/drbd/drbd-kernel-compat/gen_patch_names.c @@ -574,6 +574,9 @@ int main(int argc, char **argv) patch(1, "blk_mode_t", true, false, COMPAT_HAVE_BLK_MODE_T, "present"); + patch(1, "genl_info_userhdr", true, false, + COMPAT_HAVE_GENL_INFO_USERHDR, "present"); + /* #define BLKDEV_ISSUE_ZEROOUT_EXPORTED */ /* #define BLKDEV_ZERO_NOUNMAP */ diff --git a/drbd/drbd-kernel-compat/tests/have_genl_info_userhdr.c b/drbd/drbd-kernel-compat/tests/have_genl_info_userhdr.c new file mode 100644 index 000000000000..3c69dacce244 --- /dev/null +++ b/drbd/drbd-kernel-compat/tests/have_genl_info_userhdr.c @@ -0,0 +1,7 @@ +/* { "version": "v6.6-rc1", "commit": "bffcc6882a1bb2be8c9420184966f4c2c822078e", "comment": "genetlink: remove userhdr from struct genl_info", "author": "Jakub Kicinski <kuba@kernel.org>", "date": "Mon Aug 14 14:47:16 2023 -0700" } */ +#include <net/genetlink.h> + +void *foo(struct genl_info *info) +{ + return genl_info_userhdr(info); +} diff --git a/drbd/drbd_nl.c b/drbd/drbd_nl.c index 71ed4272614e..538c31202e4b 100644 --- a/drbd/drbd_nl.c +++ b/drbd/drbd_nl.c @@ -203,7 +203,7 @@ static struct drbd_path *first_path(struct drbd_connection *connection) static int drbd_adm_prepare(struct drbd_config_context *adm_ctx, struct sk_buff *skb, struct genl_info *info, unsigned flags) { - struct drbd_genlmsghdr *d_in = info->userhdr; + struct drbd_genlmsghdr *d_in = genl_info_userhdr(info); const u8 cmd = info->genlhdr->cmd; int err; @@ -2106,7 +2106,7 @@ static void drbd_try_suspend_al(struct drbd_device *device) static bool should_set_defaults(struct genl_info *info) { - unsigned flags = ((struct drbd_genlmsghdr*)info->userhdr)->flags; + unsigned int flags = ((struct drbd_genlmsghdr *)genl_info_userhdr(info))->flags; return 0 != (flags & DRBD_GENL_F_SET_DEFAULTS); } @@ -6279,7 +6279,7 @@ out_no_unlock: int drbd_adm_new_minor(struct sk_buff *skb, struct genl_info *info) { struct drbd_config_context adm_ctx; - struct drbd_genlmsghdr *dh = info->userhdr; + struct drbd_genlmsghdr *dh = genl_info_userhdr(info); struct device_conf device_conf; struct drbd_resource *resource; struct drbd_device *device; -- 2.42.1
