Hi, I'm happy to announce ipset 7.6. The release contains mostly bugfixes uncovered by syzbot. The fixing of "INFO: rcu detected stall in hash_xxx" is resulted faster add/del operations due to the introduced region locks instead of using a single lock to protect the set data. Please note, the oldest kernel version supported by the ipset package is now 3.11. Userspace changes: - Add checking system_power_efficient_wq in the kernel source tree - .gitignore: add temporary files to the list Kernel part changes: - netfilter: ipset: Fix forceadd evaluation path - netfilter: ipset: Correct the reported memory size - ip_set: Include kernel header instead of UAPI (Serhey Popovych) - netfilter: ipset: Fix "INFO: rcu detected stall in hash_xxx" reports - netfilter: ipset: fix suspicious RCU usage in find_set_and_id - Add compatibility support for bitmap_zalloc() and bitmap_zero() - netfilter: ipset: use bitmap infrastructure completely - netfilter: fix a use-after-free in mtype_destroy() (Cong Wang) You can download the source code of ipset from: http://ipset.netfilter.org ftp://ftp.netfilter.org/pub/ipset/ git://git.netfilter.org/ipset.git Best regards, Jozsef - E-mail : kadlec@xxxxxxxxxxxxxxxxx, kadlecsik.jozsef@xxxxxxxxx PGP key : https://wigner.hu/~kadlec/pgp_public_key.txt Address : Wigner Research Centre for Physics H-1525 Budapest 114, POB. 49, Hungary
