d098d772 - selftest: af_unix: Add msg_oob.c.

Tue, 25 Jun 2024 01:36:36 +0000

selftest: af_unix: Add msg_oob.c.AF_UNIX's MSG_OOB functionality lacked thorough testing, and we foundsome bizarre behaviour.The new selftest validates every MSG_OOB operation against TCP as areference implementation.This patch adds only a few tests with basic send() and recv() thatdo not fail.The following patches will add more test cases for SO_OOBINLINE, SIGURG,EPOLLPRI, and SIOCATMARK.Signed-off-by: Kuniyuki Iwashima Signed-off-by: Paolo Abeni List of files: /linux-6.15/tools/testing/selftests/net/af_unix/Makefile

7d139181 - selftest: af_unix: Remove test_unix_oob.c.

Tue, 25 Jun 2024 01:36:35 +0000

selftest: af_unix: Remove test_unix_oob.c.test_unix_oob.c does not fully cover AF_UNIX's MSG_OOB functionality,thus there are discrepancies between TCP behaviour.Also, the test uses fork() to create message producer, and it's noteasy to understand and add more test cases.Let's remove test_unix_oob.c and rewrite a new test.Signed-off-by: Kuniyuki Iwashima Signed-off-by: Paolo Abeni List of files: /linux-6.15/tools/testing/selftests/net/af_unix/Makefile

2aa0cff2 - selftest: af_unix: Test GC for SCM_RIGHTS.

Mon, 25 Mar 2024 20:24:25 +0000

selftest: af_unix: Test GC for SCM_RIGHTS.This patch adds test cases to verify the new GC.We run each test for the following cases: * SOCK_DGRAM * SOCK_STREAM without embryo socket * SOCK_STREAM without embryo socket + MSG_OOB * SOCK_STREAM with embryo sockets * SOCK_STREAM with embryo sockets + MSG_OOBBefore and after running each test case, we ensure that there isno AF_UNIX socket left in the netns by reading /proc/net/protocols.We cannot use /proc/net/unix and UNIX_DIAG because the embryo socketdoes not show up there.Each test creates multiple sockets in an array. We pass sockets inthe even index using the peer sockets in the odd index.So, send_fd(0, 1) actually sends fd[0] to fd[2] via fd[0 + 1].

ac011361 - af_unix: Add test for sock_diag and UDIAG_SHOW_UID.

Sun, 27 Nov 2022 01:24:12 +0000

af_unix: Add test for sock_diag and UDIAG_SHOW_UID.The test prog dumps a single AF_UNIX socket's UID with and withoutunshare(CLONE_NEWUSER) and checks if it matches the result of getuid().Without the preceding patch, the test prog is killed by a NULL derefin sk_diag_dump_uid(). # ./diag_uid TAP version 13 1..2 # Starting 2 tests from 3 test cases. # RUN diag_uid.uid.1 ...

e30cd812 - selftests: net: af_unix: Fix makefile to use TEST_GEN_PROGS

Fri, 17 Sep 2021 21:53:56 +0000

selftests: net: af_unix: Fix makefile to use TEST_GEN_PROGSMakefile uses TEST_PROGS instead of TEST_GEN_PROGS to defineexecutables. TEST_PROGS is for shell scripts that need to beinstalled and run by the common lib.mk framework. The commonframework doesn't touch TEST_PROGS when it does build and clean.As a result "make kselftest-clean" and "make clean" fail to removeexecutables. Run and install work because the common framework runsand installs TEST_PROGS. Build works because the Makefile defines"all" rule which is unnecessary if TEST_GEN_PROGS is used.Use TEST_GEN_PROGS so the common framework can handle build/run/install/clean properly.Signed-off-by: Shuah Khan Signed-off-by: David S.

314001f0 - af_unix: Add OOB support

Sun, 01 Aug 2021 07:57:07 +0000

af_unix: Add OOB supportThis patch adds OOB support for AF_UNIX sockets.The semantics is same as TCP.The last byte of a message with the OOB flag istreated as the OOB byte. The byte is separated intoa skb and a pointer to the skb is stored in unix_sock.The pointer is used to enforce OOB semantics.Signed-off-by: Rao Shoaib Signed-off-by: David S.
