* umdns: add missing syscalls to seccomp filterDaniel Golle2021-04-101-27/+30
| | | | | | | | | | | | | | | Looks like 'openat', 'pipe2' and 'ppoll' are now needed, possibly due to changes on libraries used by umdns now using slightly different calls. Found using /etc/init.d/umdns trace now use umdns, ie. cover all ubus call etc., then /etc/init.d/umdns stop find list of syscalls traced in /tmp/umdns.*.json Fixes: FS#3355 ("UMDNS: does not start on master with seccomp") Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* umdns: suppress address-of-packed-member warningKevin Darbyshire-Bryant2020-04-041-2/+2
| | | | | | | | | | | | | | | | | gcc 8 & 9 appear to be more picky with regards access alignment to packed structures, leading to this warning in dns.c: dns.c:261:2: error: converting a packed ‘struct dns_question’ pointer (alignment 1) to a ‘uint16_t’ {aka ‘short unsigned int’} pointer (alignment 2) may result in an unaligned pointer value [-Werror=address-of-packed-member] 261 | uint16_t *swap = (uint16_t *) q; Work around what I think is a false positive by turning the warning off. Not ideal, but not quite as not ideal as build failure. Signed-off-by: Kevin Darbyshire-Bryant <ldir@darbyshire-bryant.me.uk>

* umdns: remove superfluous include in init scriptJo-Philipp Wich2017-06-021-2/+0
| | | | | | | | | | | | | The umdns init script includes function/network.sh globally, outside of any service procedure. This causes init script activation to fail in buildroot and IB context if umdns is set to builtin. Additionally, the network.sh helper is not actually used. Drop the entire include in order to repair init script activation in build host context. Fixes FS#658. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

* umdns: update to the version 2017-03-21Rafał Miłecki2017-03-211-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | This includes following changes: 480d7bc Fix sending unicast questions on cache expire a0403cd Keep source sockaddr for every cached DNS record 1478293 Fix code freeing cached non-A(AAA) records too early 9f1cc22 Fix replying to "QU" questions received on unicast interface 943bedb Fix reading port of incoming packets c725494 Use MCAST_PORT define for port 5353 ce7e9e9 Use one define for DNS-Based Service Discovery service name e1bacef Drop entries cached for interface we're going to delete 496aeba Fix comment typo in cache_gc_timer f89986b Fix refreshing cached A(AAA) records that expire Previous updates made umdns work as expected on startup but there were still many bugs. They were mostly related to runtime - cache management and requests + responses. E.g. umdns was never able to send question on DNS record expire. It was also ignoring all incoming unicast questions. Since these issues are quite serious it makes sense to backport this update to the stable branch. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

* mdns: update and rename package to the umdnsRafał Miłecki2017-02-154-0/+136
This update includes numerous small fixes for: 1) Interfaces setup 2) Packets parsing 3) Sending replies Without this there were multiple problems with exchanging information between (u)mdns and other implementations (including (u)mdns as well). This also follows project rename to umdns which was required to avoid confusion with Apple's mdnsd from mDNSResponder project. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
