2020-08-03Put the code handling \} into a new function roff_cond_checkend()schwarze8-65/+159
and call that function not only from both places where copies existed - when processing text lines and when processing request/macro lines in conditional block scope - but also when closing a macro definition request, such that this construction works: .if n \{.de macroname macro content .. \} ignored arguments .macroname This fixes a bug reported by John Gardner <gardnerjohng at gmail dot com>. While here, avoid a confusing decrement of the line scope counter in roffnode_cleanscope() for conditional blocks that do not have line scope in the first place (no functional change for this part). Also improve validation of an internal invariant in roff_cblock() and polish some comments.

2020-08-03add "sample NUM" so you can ask to capture 1/NUM packets from a filter.dlg5-6/+33
the use of the sample keyword matches similar config in other products. NUM can be a number between 2 and 1048576, and is used to divide 0x100000000 into a threshold that is then compared against a randomly generated number produced by a load of BPF_RND. having sampling as part of the grammar means you can write things like "icmp or sample 128". this lets you capture all icmp traffic and a sample of the rest of the traffic. ok jmatthew@ kn@ tb@

2020-08-03add support for handling loads from BPF_RND.dlg7-10/+38
this adds "rnd" and "random" as keywords in the grammar, and handles them as an arithmetic operator. the decoder recognises the load, so tcpdump can print it as 'ld #random'. most of the handling is copied from the "len"/"length" keywoard handling that generates and decodes a load of the actual wire length of the packet. ok jmatthew@ tb@ kn@
2020-08-03add a BPF_RND load location that provides a random value.dlg2-2/+8
this will be used so a bpf filter can make a decision based on a random number, which in turn will be used so a filter can perform random sampling of packets rather than capturing all packets. random sampling means that we don't have to figure out how to make bpf coordinate multiple concurrent calls to do counter based sampling. BPF_RND is currently backed with arc4random. discussed with many including jmatthew@, alex wilson, claudio@, sthen@, deraadt@, and tb@ ok kn@ tb@ jmatthew@ i call this extended bpf... xBPF.

2020-08-02Squelch warning by using idiom from libc bcrypt(3)tb1-2/+2
Clang 10 warns about the expression sizeof(cdata) / sizeof(uint64_t) as cdata is an array of uint32_t and it expects that the intent of this is to compute the number of array elements. Use BCRYPT_WORDS / 2 instead. Same diff as millert's commit sys/lib/libsa/bcrypt_pbkdf.c -r1.2, which was ok kettenis. deraadt confirms that this satisfies clang 10.

2020-08-02Add missing rtable(4) check in rip6_input()kn1-1/+5
Copied over from sys/netinet/raw_ip.c:rip_input() where it appeared with initial support for multiple routing tables. This enforces separation between multiple raw sockets in different routing tables, i.e. one must not see packets from the other if the rtable differs. Observed with ping6(8)'s "-v" showing all ICMPv6 packets on its raw socket including those produced by another ping6 with "-V1". florian reported IPv6 route advertisments in one routing table appearing on raw sockets in other routing tables as well. OK claudio florian
2020-08-02Make iwx(4) match any AX200 device again.stsp1-12/+2
In case of AX201 we need to be careful about which devices are matched by the driver because devices with technical differences share the same PCI product ID. The driver must additionally match against a table of known PCI subsystem product IDs to identify an AX201 device correctly. For consistency, I wrote similar matching code for AX200 devices. This matches my AX200 device correctly but fails to recognize some other devices which were previously attached and working. Turns out the Linux driver seems to use AX200 subsystem product IDs merely for marketing purposes. It makes the operating system advertise some AX200 devices with distinct trademarked names. There are no technical differences that concern the driver and there is no exhaustive list of possible AX200 subsystem product IDs. So just match them all. Problem reported by Bobby Reynolds.
2020-08-02Check the return value of tls1_enc() in the write path.jsing2-6/+6
The write path can return a failure in the AEAD path and there is no reason not to check a return value. Spotted by tb@ during another review. ok tb@

2020-08-01Clean up/simplify more of the dtls1/ssl3 record writing code:jsing2-73/+34
- Make the DTLS code much more consistent with the ssl3 code. - Avoid assigning wr->input and wr->length just so they can be used as arguments to memcpy(). - Remove the arc4random_buf() call for the explicit IV, since tls1_enc() already does this for us. ok tb@

Matching firmware can be installed with fw_update(1). Align our device initialization sequence more closely to how Linux does it. We still use a different MSI-X configuration but register values written up to that point are now identical. patrick@ provided help with debugging several issues along way, thanks!

2020-08-01Add support for remote coverage to kcov. Remote coverage is collectedanton9-20/+433
from threads other than the one currently having kcov enabled. A thread with kcov enabled occasionally delegates work to another thread, collecting coverage from such threads improves the ability of syzkaller to correlate side effects in the kernel caused by issuing a syscall. Remote coverage is divided into subsystems. The only supported subsystem right now collects coverage from scheduled tasks and timeouts on behalf of a kcov enabled thread. In order to make this work `struct task' and `struct timeout' must be extended with a new field keeping track of the process that scheduled the task/timeout. Both aforementioned structures have therefore increased with the size of a pointer on all architectures. The kernel API is documented in a new kcov_remote_register(9) manual. Remote coverage is also supported by kcov on NetBSD and Linux. ok mpi@

atapiscsi is not needed here. (well maybe it changes the behaviour of the pciide subsystem a tiny bit at attach-time, but we don't have the downstream cd(4) device to attach, so let's try without)
2020-07-31Use consistent types in comparison to fix build with clang 10.visa2-2/+2
Instead of just checking if *namep is NULL, also check if the string pointed by *namep is empty. This is probably the original intent of the code. OK kettenis@ jsg@ deraadt@
