net: remove noblock parameter from skb_recv_datagram()

2022-04-06T12:45:26Z

skb_recv_datagram() has two parameters 'flags' and 'noblock' that are merged inside skb_recv_datagram() by 'flags | (noblock ? MSG_DONTWAIT : 0)' As 'flags' may contain MSG_DONTWAIT as value most callers split the 'flags' into 'flags' and 'noblock' with finally obsolete bit operations like this: skb_recv_datagram(sk, flags & ~MSG_DONTWAIT, flags & MSG_DONTWAIT, &rc); And this is not even done consistently with the 'flags' parameter. This patch removes the obsolete and costly splitting into two parameters and only performs bit operations when really needed on the caller side. One missing conversion thankfully reported by kernel test robot. I missed to enable kunit tests to build the mctp code.

mISDN: Fix memory leak in dsp_pipeline_build()

2022-03-05T12:04:14Z

dsp_pipeline_build() allocates dup pointer by kstrdup(cfg), but then it updates dup variable by strsep(&dup, "|"). As a result when it calls kfree(dup), the dup variable contains NULL.

mISDN: change function names to avoid conflicts

2021-12-28T12:12:04Z

As we build for mips, we meet following error. l1_init error with multiple definition. Some architecture devices usually marked with l1, l2, lxx as the start-up phase. so we change the mISDN function names, align with Isdnl2_xxx. mips-linux-gnu-ld: drivers/isdn/mISDN/layer1.o: in function `l1_init': (.text+0x890): multiple definition of `l1_init'; \ arch/mips/kernel/bmips_5xxx_init.o:(.text+0xf0): first defined here make[1]: *** [home/mips/kernel-build/linux/Makefile:1161: vmlinux] Error 1 Signed-off-by: wolfgang huang Reported-by: k2ci Signed-off-by: David S.
