* iptables: set-dscpmark follow upstreamimg attemptKevin Darbyshire-Bryant2020-01-311-1/+1
| | | | | | | | | | | I'm having another attempt at trying to getting the 'store dscp into conntrack connmark' functionality into upstream kernel, since the restore function (act_ctinfo) has been accepted. The syntax has changed from 'savedscp' to 'set-dscpmark' since that conforms more closely with existing functionality. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

* build: include BUILD_VARIANT in PKG_BUILD_DIRJeffery To2019-08-051-2/+0
| | | | | | | | | | | This changes the default PKG_BUILD_DIR to take BUILD_VARIANT into account (if set), so that packages do not need to manually override PKG_BUILD_DIR just to handle variants. This also updates most base packages with variants to use the updated default PKG_BUILD_DIR. Signed-off-by: Jeffery To <jeffery.to@gmail.com>

* iproute2: add tc action ctinfo supportKevin Darbyshire-Bryant2019-06-072-1/+595
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the userspace control portion of the backported kernelspace act_ctinfo. ctinfo is a tc action restoring data stored in conntrack marks to various fields. At present it has two independent modes of operation, restoration of DSCP into IPv4/v6 diffserv and restoration of conntrack marks into packet skb marks. It understands a number of parameters specific to this action in additional to the usual action syntax. Each operating mode is independent of the other so all options are optional, however not specifying at least one mode is a bit pointless. Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE] [CONTROL] [index <INDEX>] DSCP mode dscp enables copying of a DSCP stored in the conntrack mark into the ipv4/v6 diffserv field. The mask is a 32bit field and specifies where in the conntrack mark the DSCP value is located. It must be 6 contiguous bits long. eg. 0xfc000000 would restore the DSCP from the upper 6 bits of the conntrack mark. The DSCP copying may be optionally controlled by a statemask. The statemask is a 32bit field, usually with a single bit set and must not overlap the dscp mask. The DSCP restore operation will only take place if the corresponding bit/s in conntrack mark ANDed with the statemask yield a non zero result. eg. dscp 0xfc000000 0x01000000 would retrieve the DSCP from the top 6 bits, whilst using bit 25 as a flag to do so. Bit 26 is unused in this example. CPMARK mode cpmark enables copying of the conntrack mark to the packet skb mark. In this mode it is completely equivalent to the existing act_connmark action. Additional functionality is provided by the optional mask parameter, whereby the stored conntrack mark is logically ANDed with the cpmark mask before being stored into skb mark. This allows shared usage of the conntrack mark between applications. eg. cpmark 0x00ffffff would restore only the lower 24 bits of the conntrack mark, thus may be useful in the event that the upper 8 bits are used by the DSCP function. Usage: ... ctinfo [dscp mask [statemask]] [cpmark [mask]] [zone ZONE] [CONTROL] [index <INDEX>] where : dscp MASK is the bitmask to restore DSCP STATEMASK is the bitmask to determine conditional restoring cpmark MASK mask applied to restored packet mark ZONE is the conntrack zone CONTROL := reclassify | pipe | drop | continue | ok | goto chain <CHAIN_INDEX> Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

* iproute2: simplify Makefile, patches and fix feature detectionTony Ambardar2019-02-113-20/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Compile-based feature detection (e.g. xtables, ipset support) was broken due to silent compilation errors in the configure script, caused by a Makefile variable KERNEL_INCLUDE referring to kernel build headers. Use userspace headers by setting the same "user_headers" kernel include path as used for the iptables build. Remove redundant or unused Build/Configure definitions from package Makefile, including KERNEL_INCLUDE, LIBC_INCLUDE and DBM includes. Don't pass LDFLAGS within MAKE_FLAGS as this interferes with LDFLAGS in tc/Makefile and masks a link parameter ("-Wl,-export-dynamic"). Instead, use standard TARGET_LDFLAGS. Replace EXTRA_CCOPTS in MAKE_FLAGS with cleaner TARGET_CPPFLAGS, and also drop now unneeded patch 150-extra-ccopts.patch. Enable defining XT_LIB_DIR from Makefile, needed to set the iptables modules directory to something other than /lib/xtables, and also add libxtables dependency. Both are needed with working xtables detection. Note that libxtables is also pulled in by iptables, firewall or luci, so this change has no size impact in most cases.

* iproute2: only link libelf where neededJo-Philipp Wich2018-12-192-2/+62
| | | | | | | | | | | | | | | | | | | | | The iproute2 build system links libelf support to every utility while only the tc program actually requires libelf specific functionality. Unfortunately the BPF ELF functionality is not confined into an own compilation unit but added to the existing bpf.c sources of the shared static libutil.a, causing every iproute2 applet to pick up an implicit libelf.so dependency. In order to avoid this requirement, patch the iproute2 build system to create both a libutil.a and a libutil-elf.a, with the former being built without libelf functionality and to only link the tc applet with the libelf enabled libutil. Finally, make the tc package depend on libelf to solve compilation errors. Ref: https://github.com/openwrt/packages/issues/7728 Fixes: FS#2011 Signed-off-by: Jo-Philipp Wich <jo@mein.io>

| | | | | | | | | | | | | | | | | | | iproute2's tc was updated to support the recently upstreamed cake qdisc. Backport this canonical support from upstream into iproute2 v4.17 There is no kernel kmod/userspace tc ABI change in this release from the previous package bump, so everyone can breath a sigh of relief. This is largely a code style change, the exception to prove the rule: option 'autorate_ingress' has been changed to 'autorate-ingress' to fit in with upstream option naming expectations. No openwrt package (e.g. sqm-scripts) has knowledge of 'autorate_ingress' thus only users who made their own scripts or used it within the 'dangerous configuration' options of sqm-scripts will be affected.

| | | | | | | | | | | | | | | | | | | | | | | The sender domain has a DMARC Reject/Quarantine policy which disallows sending mailing list messages using the original "From" header. To mitigate this problem, the original message has been wrapped automatically by the mailing list software. print_uint() will silently promote its variable type to uint64_t, but there is nothing that ensures that the format string specifier passed along with it fits (and the function name suggest to pass "%u"). Fix this by changing print_uint() to use a native 'unsigned int' type, and introduce a separate print_u64() function for printing 64-bit values. All call sites that were actually printing 64-bit values using print_uint() are converted to use print_u64() instead. Since print_int() was already using native int types, just add a print_s64() to match, but don't convert any call sites.

| | | | | | | | | | | | | | | | | | | | | | Cake in kernel space now splits stats structure handling across netlink messages to reduce stack usage issue flagged by upstream kernel checks. Update user space (tc) qdisc handling to understand this new regime. Cake also reports packet overheads & compensation in a different way so add display code for this. e.g. 'tc -s qdisc show dev eth0' reports this extra detail: min/max transport layer size: 28 / 1500 min/max overhead-adjusted size: 65 / 1550 average transport hdr offset: 14 Cake also supports output in JSON format.

* iproute2: fix hidden uint to uin64_t promotion in json_printKevin Darbyshire-Bryant2018-03-192-1/+66
| | | | | | | | | | | | | | | | | | | | | | | | | print_int used 'int' type internally, whereas print_uint used 'uint64_t' These helper functions eventually call vfprintf(fp, fmt, args) which is a variable argument list function and is dependent upon 'fmt' containing correct information about the length of the passed arguments. Unfortunately print_int v print_uint offered no clue to the programmer that internally passed ints to print_uint were being promoted to 64bits, thus the format passed in 'fmt' string vs the actual passed integer could be different lengths. This is even more interesting on big endian architectures where 'vfprintf' would be looking in the middle of an int64 type. Symptoms of this included tc qdisc showing bizarre values for a variety of fields across a variety of qdiscs (e.g. refcnt, flows, quantum) print_u/int now stick with native int size. A similar patch has been sent upstream. Fixes FS#1425 Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>
