sctp: get netns from asoc and ep base

2019-12-10T04:14:01Z

Commit 312434617cb1 ("sctp: cache netns in sctp_ep_common") set netns in asoc and ep base since they're created, and it will never change. It's a better way to get netns from asoc and ep base, comparing to calling sock_net(). This patch is to replace them. v1->v2: - no change.

sctp: add SCTP_SEND_FAILED_EVENT event

2019-10-10T00:06:58Z

This patch is to add a new event SCTP_SEND_FAILED_EVENT described in rfc6458#section-6.1.11. It's a update of SCTP_SEND_FAILED event: struct sctp_sndrcvinfo ssf_info is replaced with struct sctp_sndinfo ssfe_info in struct sctp_send_failed_event. SCTP_SEND_FAILED is being deprecated, but we don't remove it in this patch. Both are being processed in sctp_datamsg_destroy() when the corresp event flag is set.

sctp: chunk.c: correct format string for size_t in printk

2019-02-28T18:33:40Z

According to Documentation/core-api/printk-formats.rst, size_t should be printed with %zu, rather than %Zu. In addition, using %Zu triggers a warning on clang (-Wformat-extra-args): net/sctp/chunk.c:196:25: warning: data argument not used by format string [-Wformat-extra-args] __func__, asoc, max_data); ~~~~~~~~~~~~~~~~^~~~~~~~~ ./include/linux/printk.h:440:49: note: expanded from macro 'pr_warn_ratelimited' printk_ratelimited(KERN_WARNING pr_fmt(fmt), ##__VA_ARGS__) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~ ./include/linux/printk.h:424:17: note: expanded from macro 'printk_ratelimited' printk(fmt, ##__VA_ARGS__); \ ~~~ ^ Fixes: 5b5e0928f742 ("lib/vsprintf.c: remove %Z support") Link: https://github.com/ClangBuiltLinux/linux/issues/378 Signed-off-by: Matthias Maennich Acked-by: Marcelo Ricardo Leitner Signed-off-by: David S.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

2018-12-10T05:43:31Z

Several conflicts, seemingly all over the place. I used Stephen Rothwell's sample resolutions for many of these, if not just to double check my own work, so definitely the credit largely goes to him. The NFP conflict consisted of a bug fix (moving operations past the rhashtable operation) while chaning the initial argument in the function call in the moved code. The net/dsa/master.c conflict had to do with a bug fix intermixing of making dsa_master_set_mtu() static with the fixing of the tagging attribute location. cls_flower had a conflict because the dup reject fix from Or overlapped with the addition of port range classifiction. __set_phy_supported()'s conflict was relatively easy to resolve because Andrew fixed it in both trees, so it was just a matter of taking the net-next copy. Or at least I think it was :-) Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup() intermixed with changes on how the sdif and caller_net are calculated in these code paths in net-next. The remaining BPF conflicts were largely about the addition of the __bpf_md_ptr stuff in 'net' overlapping with adjustments and additions to the relevant data structure where the MD pointer macros are used.

sctp: frag_point sanity check

2018-12-06T04:37:52Z

If for some reason an association's fragmentation point is zero, sctp_datamsg_from_user will try to endlessly try to divide a message into zero-sized chunks. This eventually causes kernel panic due to running out of memory. Although this situation is quite unlikely, it has occurred before as reported. I propose to add this simple last-ditch sanity check due to the severity of the potential consequences.

sctp: add subscribe per asoc

2018-11-19T20:25:43Z

The member subscribe should be per asoc, so that sockopt SCTP_EVENT in the next patch can subscribe a event from one asoc only. Signed-off-by: Xin Long Signed-off-by: David S. Miller

sctp: define subscribe in sctp_sock as __u16

2018-11-19T20:25:43Z

The member subscribe in sctp_sock is used to indicate to which of the events it is subscribed, more like a group of flags. So it's better to be defined as __u16 (2 bytpes), instead of struct sctp_event_subscribe (13 bytes). Note that sctp_event_subscribe is an UAPI struct, used on sockopt calls, and thus it will not be removed. This patch only changes the internal storage of the flags.

net/sctp: Make wrappers for accessing in/out streams

2018-08-11T19:25:15Z

This patch introduces wrappers for accessing in/out streams indirectly. This will enable to replace physically contiguous memory arrays of streams with flexible arrays (or maybe any other appropriate mechanism) which do memory allocation on a per-page basis.
