lib/crc: remove CONFIG_LIBCRC32CNow that LIBCRC32C does nothing besides select CRC32, make every optionthat selects LIBCRC32C instead select CRC32 directly. Then removeLIBCRC32C.Reviewed-by: Christoph Hellwig Reviewed-by: "Martin K.

Wed, 17 May 2023 03:08:49 +0000

ipvs: increase ip_vs_conn_tab_bits range for 64BITCurrent range [8, 20] is set purely due to historical reasonsbecause at the time, ~1M (2^20) was considered sufficient.With this change, 27 is the upper limit for 64-bit, 20 otherwise.Previous change regarding this limit is here.Link: https://lore.kernel.org/all/86eabeb9dd62aebf1e2533926fdd13fed48bab1f.1631289960.git.aclaudi@redhat.com/T/#uSigned-off-by: Abhijeet Rastogi Acked-by: Julian Anastasov Acked-by: Simon Horman Signed-off-by: Pablo Neira Ayuso List of files: /linux-6.15/net/netfilter/ipvs/Kconfig

ipvs: Complete IPv6 fragment handling for IPVSIPVS now supports fragmented packets, with support from nf_conntrack_reasm.cBased on patch from: Hans Schillstrom.IPVS do like conntrack i.e. use the skb->nfct_reasm(i.e. when all fragments is collected, nf_ct_frag6_output()starts a "re-play" of all fragments into the interruptedPREROUTING chain at prio -399 (NF_IP6_PRI_CONNTRACK_DEFRAG+1)with nfct_reasm pointing to the assembled packet.)Notice, module nf_defrag_ipv6 must be loaded for this to work.Report unhandled fragments, and recommend user to load nf_defrag_ipv6.To handle fw-mark for fragments. Add a new IPVS hook into preroutingchain at prio -99 (NF_IP6_PRI_NAT_DST+1) to catch fragments, and copyfw-mark info from the first packet with an upper layer header.IPv6 fragment handling should be the last thing on the IPVS IPv6missing support list.Signed-off-by: Jesper Dangaard Brouer Signed-off-by: Hans Schillstrom Acked-by: Julian Anastasov Signed-off-by: Simon Horman List of files: /linux-6.15/net/netfilter/ipvs/Kconfig

63dca2c0 - ipvs: Fix faulty IPv6 extension header handling in IPVS

Wed, 26 Sep 2012 12:06:41 +0000

ipvs: Fix faulty IPv6 extension header handling in IPVSIPv6 packets can contain extension headers, thus its wrong to assumethat the transport/upper-layer header, starts right after (structipv6hdr) the IPv6 header. IPVS uses this false assumption, and willwrite SNAT & DNAT modifications at a fixed pos which will corrupt themessage.To fix this, proper header position must be found before modifyingpackets. Introducing ip_vs_fill_iph_skb(), which uses ipv6_find_hdr()to skip the exthdrs. It finds (1) the transport header offset, (2) theprotocol, and (3) detects if the packet is a fragment.Note, that fragments in IPv6 is represented via an exthdr. Thus, thisis detected while skipping through the exthdrs.This patch depends on commit 84018f55a: "netfilter: ip6_tables: add flags parameter to ipv6_find_hdr()"This also adds a dependency to ip6_tables.Originally based on patch from: Hans SchillstromkABI notes:Changing struct ip_vs_iphdr is a potential minor kABI breaker,because external modules can be compiled with another version ofthis struct. This should not matter, as they would most-likelybe using a compiled-in version of ip_vs_fill_iphdr(). Whenrecompiled, they will notice ip_vs_fill_iphdr() no longer exists,and they have to used ip_vs_fill_iph_skb() instead.Signed-off-by: Jesper Dangaard Brouer Acked-by: Julian Anastasov Signed-off-by: Simon Horman List of files: /linux-6.15/net/netfilter/ipvs/Kconfig

76ad94fc - IPVS: Modify the SH scheduler to use weights

Thu, 08 Dec 2011 15:55:09 +0000

IPVS: Modify the SH scheduler to use weightsModify the algorithm to build the source hashing hash table to addextra slots for destinations with higher weight. This has the effectof allowing an IPVS SH user to give more connections to hosts thathave been configured to have a higher weight.The reason for the Kconfig change is because the size of the hash tablebecomes more relevant/important if you decide to use the weights in themanner this patch lets you. It would be conceivable that someone mightneed to increase the size of that table to accommodate theirconfiguration, so it will be handy to be able to do that through theregular configuration system instead of editing the source.Signed-off-by: Michael Maxim Signed-off-by: Simon Horman Signed-off-by: Pablo Neira Ayuso List of files: /linux-6.15/net/netfilter/ipvs/Kconfig
