2019-04-18unfold some compound operations to make this easier to followtedu1-6/+11
2019-04-18Always check for namespace collisions on table commandskn1-3/+3
`-t table -T add|replace ...' would only check for duplicate tables in case addresses where actually to the table. Instead of using a positive number of added addresses as prove for successful table operations, rely on the fact that CREATE_TABLE() is guaranteed to be called only if pf(4) can be accessed, that is warn_duplicate_tables() will return. This improves duplicate detection rate as warnings are now also emitted even when table commands eventually leave tables unchanged. OK benno sashan
2019-04-18Fix table definition parsing as unprivileged userkn1-2/+7
revision 1.689 introduced warn_duplicate_tables() unconditionally, breaking the parser on tables withs insufficient permissions to open pf(4): $ echo 'table <t>' | pfctl -nf- pfctl: pfr_get_tables: Bad file descriptor So simply check whether pfctl is able to get the table list first. If not, instead of silently avoiding namespace collision checks, print a brief notice iff `-v' is given to help finding duplicate definitions by hand: $ echo 'table <t>' | ./obj/pfctl -vnf- table <t> stdin:1: skipping duplicate table checks for <t> Reported by Rivo Nurges, thanks! OK benno sashan

2019-04-16Rewrite & fix X509V3_add_value()tb1-17/+24
X509V3_add_value() helpfully allocates a STACK_OF(CONF_VALUE) if it receives a pointer to a NULL pointer. If anything fails along the way, it is however the caller's responsibility to free it. This can easily be fixed by freeing *extlist in the error path and zeroing it to avoid a double free if there happens to be a caller out there that avoids the leak. Polish a few things so the function conforms a bit better to our usual style. tweak & ok jsing

2019-04-16have another go at tx mitigationdlg4-10/+46
the idea is to call the hardware transmit routine less since in a lot of cases posting a producer ring update to the chip is (very) expensive. it's better to do it for several packets instead of each packet, hence calling this tx mitigation. this diff defers the call to the transmit routine to a network taskq, or until a backlog of packets has built up. dragonflybsd uses 16 as the size of it's backlog, so i'm copying them for now. i've tried this before, but previous versions caused deadlocks. i discovered that the deadlocks in the previous version was from ifq_barrier calling taskq_barrier against the nettq. interfaces generally hold NET_LOCK while calling ifq_barrier, but the tq might already be waiting for the lock we hold. this version just doesnt have ifq_barrier call taskq_barrier. it instead relies on the IFF_RUNNING flag and normal ifq serialiser barrier to guarantee the start routine wont be called when an interface is going down. the taskq_barrier is only used during interface destruction to make sure the task struct wont get used in the future, which is already done without the NET_LOCK being held. tx mitigation provides a nice performanace bump in some setups. up to 25% in some cases. tested by tb@ and hrvoje popovski (who's running this in production). ok visa@

2019-04-15ethtool indicates that QSFP, QSFP+ and QSFP28 are all SFF-8636 compat.dlg1-1/+3
2019-04-15follow the basic xfp support with basic qsfp+ supportdlg1-29/+51
qsfp was originally defined in SFF-8436, but the management interface now seems to be managed in SFF-8636, so this uses sff8636 as a prefix for qsfp things. the same spec applies to qsfp+ and probably qsfp28. XFP and QSFP share a bunch of offsets for where strings are located, so this factors out the printing of those strings from the xfp code and uses it from both the xfp and qsfp handling. i have a qsfp+ to 4x sfp+ cable that looks like this with the new code: transceiver: QSFP+ model: Amphenol 601110005 rev A serial: CN0HVVVFxxxxxxx date: 2013-04-18 if i ever get a pair of optics i can work on the diags
