net: Convert proto_ops connect() callbacks to use sockaddr_unsized

2025-11-05T03:10:32+00:00

Update all struct proto_ops connect() callback function prototypes from "struct sockaddr *" to "struct sockaddr_unsized *" to avoid lying to the compiler about object sizes. Calls into struct proto handlers gain casts that will be removed in the struct proto conversion patch. No binary changes expected.

net/x25: Remove unused x25_terminate_link()

2025-07-15T00:19:13+00:00

x25_terminate_link() has been unused since the last use was removed in 2020 by: commit 7eed751b3b2a ("net/x25: handle additional netdev events") Remove it.

net: make sk->sk_rcvtimeo lockless

2025-06-24T00:05:12+00:00

Followup of commit 285975dd6742 ("net: annotate data-races around sk->sk_{rcv|snd}timeo"). Remove lock_sock()/release_sock() from ksmbd_tcp_rcv_timeout() and add READ_ONCE()/WRITE_ONCE() where it is needed. Also SO_RCVTIMEO_OLD and SO_RCVTIMEO_NEW can call sock_set_timeout() without holding the socket lock.

treewide, timers: Rename from_timer() to timer_container_of()

2025-06-08T07:07:37+00:00

Move this API to the canonical timer_*() namespace. [ tglx: Redone against pre rc1 ] Signed-off-by: Ingo Molnar Signed-off-by: Thomas Gleixner Link: https://lore.kernel.org/all/aB2X0jCKQO56WdMt@gmail.com

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

net: change proto and proto_ops accept type

2024-05-14T00:19:09+00:00

Rather than pass in flags, error pointer, and whether this is a kernel invocation or not, add a struct proto_accept_arg struct as the argument. This then holds all of these arguments, and prepares accept for being able to pass back more information. No functional changes in this patch. Acked-by: Jakub Kicinski Signed-off-by: Jens Axboe

ax.25: x.25: Remove the now superfluous sentinel elements from ctl_table array

2024-05-03T12:29:43+00:00

This commit comes at the tail end of a greater effort to remove the empty elements at the end of the ctl_table arrays (sentinels) which will reduce the overall build time size of the kernel and run time memory bloat by ~64 bytes per sentinel (further information Link : https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/) Avoid a buffer overflow when traversing the ctl_table by ensuring that AX25_MAX_VALUES is the same as the size of ax25_param_table. This is done with a BUILD_BUG_ON where ax25_param_table is defined and a CONFIG_AX25_DAMA_SLAVE guard in the unnamed enum definition as well as in the ax25_dev_device_up and ax25_ds_set_timer functions. The overflow happened when the sentinel was removed from ax25_param_table. The sentinel's data element was changed when CONFIG_AX25_DAMA_SLAVE was undefined. This had no adverse effects as it still stopped on the sentinel's null procname but needed to be addressed once the sentinel was removed. Signed-off-by: Joel Granados Signed-off-by: David S. Miller

net/x25: fix incorrect parameter validation in the x25_getsockopt() function

2024-03-11T09:53:22+00:00

The 'len' variable can't be negative when assigned the result of 'min_t' because all 'min_t' parameters are cast to unsigned int, and then the minimum one is chosen. To fix the logic, check 'len' as read from 'optlen', where the types of relevant variables are (signed) int.

net: x25: remove dead links from Kconfig

2024-03-08T04:24:35+00:00

Remove the "You can read more about X.25 at" links provided in Kconfig as they have not pointed at any relevant pages for quite a while. An old copy of https://www.sangoma.com/tutorials/x25/ can be retrieved via https://archive.org/web/ but nothing useful seems to have been preserved for http://docwiki.cisco.com/wiki/X.25 For the sake of necromancy and those who really did want to read more about X.25, a previous incarnation of Kconfig included a link to: http://www.cisco.com/univercd/cc/td/doc/product/software/ios11/cbook/cx25.htm Which can still be read at: https://web.archive.org/web/20071013101232/http://cisco.com/en/US/docs/ios/11_0/router/configuration/guide/cx25.html Signed-off-by: Justin Swartz Acked-by: Martin Schiller Link: https://lore.kernel.org/r/20240306112659.25375-1-justin.swartz@risingedge.co.za Signed-off-by: Jakub Kicinski
