* ss: re-add TIPC query supportMatthieu Baerts2022-10-201-0/+1
| | | | | | | | | | | | | | | | | TIPC support has been introduced in 'iproute-master' (not -next) in commit 5caf79a0 ("ss: Add support for TIPC socket diag in ss tool"), at the same time a refactoring introducing filter_db_parse() was done, see commit 67d5fd55 ("ss: Put filter DB parsing into a separate function") from iproute2-next. When the two commits got merged, the support for TIPC has been apparently accidentally dropped. This simply adds the missing entry for TIPC.

* ss: Shorter display format for TLS zerocopy sendfileMaxim Mikityanskiy2022-06-121-2/+3
| | | | | | | | | | | | | | | Commit 21c07b45688f ("ss: Show zerocopy sendfile status of TLS sockets") started displaying the activation status of zerocopy sendfile on TLS sockets, exposed via sock_diag. This commit makes the format more compact: the flag's name is shorter and is printed only when the feature is active, similar to other flag options. The flag's name is also generalized ("sendfile" -> "tx") to embrace possible future optimizations, and includes an explicit indication that the underlying data must not be modified during transfer ("ro").

* ss: Introduce -T, --threads optionPeilin Ye2022-05-301-29/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The -p, -Z and -z options only show process (thread group leader) information. For example, if the thread group leader has exited, but another thread in the group is still using a socket, ss -[pZz] does not show it. Add a new option, -T (--threads), to show thread information. It implies the -p option. For example, imagine process A and thread B (in the same group) using the same socket. ss -p only shows A: $ ss -ltp "sport = 1234" State Recv-Q Send-Q Local Address:Port Peer Address:Port Process LISTEN 0 100 0.0.0.0:1234 0.0.0.0:* users:(("test",pid=2932547,fd=3)) ss -T shows A and B: $ ss -ltT "sport = 1234" State Recv-Q Send-Q Local Address:Port Peer Address:Port Process LISTEN 0 100 0.0.0.0:1234 0.0.0.0:* users:(("test",pid=2932547,tid=2932548,fd=3),("test",pid=2932547,tid=2932547,fd=3)) If -T is used, -Z and -z also show SELinux contexts for threads.

* ss: remove an implicit dependency on rpcinfoAndrea Claudi2022-03-231-20/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ss uses rpcinfo to get info about rpc services socket. This makes it dependent on a tool not included in iproute2, and makes it impossible to get info on rpc sockets if rpcinfo is not installed. This reworks init_service_resolver() to use libtirpc, thus avoiding the implicity dependency on rpcinfo. Moreover, this also makes it possible to display info about ipv6 rpc socket that are not included in the rpcinfo -p output. For example, before this patch: $ ss -rtap LISTEN 0 5 localhost:ipp [::]:* users:(("cupsd",pid=1600,fd=9)) LISTEN 0 64 [::]:34265 [::]:* LISTEN 0 64 [::]:rpc.nfs_acl [::]:* LISTEN 0 128 [::]:42253 [::]:* users:(("rpc.statd",pid=146164,fd=12)) After this patch: $ ss -rtap LISTEN 0 5 localhost:ipp [::]:* users:(("cupsd",pid=1600,fd=9)) LISTEN 0 64 [::]:rpc.nlockmgr [::]:* LISTEN 0 64 [::]:rpc.nfs_acl [::]:* LISTEN 0 128 [::]:rpc.status [::]:* users:(("rpc.statd",pid=146164,fd=12)) Signed-off-by: Andrea Claudi <aclaudi@redhat.com> Signed-off-by: David Ahern <dsahern@kernel.org>

| | | | | | | | | | | | | | | | Jonas reports that ss -awp does not display any RAW sockets on a Knoppix 4.4 kernel. sockdiag_send() diverts to tcpdiag_send() to try the older netlink interface. tcpdiag_send() works for TCP and DCCP but not other protocols. Instead of rejecting unsupported protocols (and missing RAW and SCTP) match on supported ones.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sport and dport conditions in expressions were inconsistent on whether there should be a ":" at the beginning of the port when only a port was provided depending on the family. The link and netlink families required a ":" to work. The vsock family required the ":" to be absent. The inet and inet6 families work with or without a leading ":". This makes the leading ":" optional in all cases, so if sport or dport are used, then it works with a leading ":" or without one, as inet and inet6 did.

However, if the family in the host condition is different than the the last -f option, then which family is actually used depends on the order that different families are checked. This changes parse_hostcond to check all family prefixes before parsing the rest of the address, so that the host condition's family always has a higher priority than the "preferred" family.

These features work based on cgroup v2 ID field in the socket (kernel should be compiled with CONFIG_SOCK_CGROUP_DATA). Cgroup information can be obtained by specifying --cgroup flag and now contains only pathname. For faster pathname lookups cgroup cache is implemented. This cache is filled on ss startup and missed entries are resolved and saved on the fly. Cgroup filter extends EXPRESSION and allows to specify cgroup pathname (relative or absolute) to obtain sockets attached only to this cgroup. Filter syntax: ss [ cgroup PATHNAME ] Examples: ss -a cgroup /sys/fs/cgroup/unified (or ss -a cgroup .) ss -a cgroup /sys/fs/cgroup/unified/cgroup1 (or ss -a cgroup cgroup1) v2: - style fixes (David Ahern) Signed-off-by: Dmitry Yakunin <zeil@yandex-team.ru> Signed-off-by: David Ahern <dsahern@gmail.com>

Previous logic was checking if fread(3) read *at least* required ammount of data, now code checks if fread(3) read *exactly* expected ammount of data. This makes sense because code parses very specific binary file, and reading even 1 less/more byte than expected, will later corrupt data anyway.
