1. two spelling mistakes. 2. change references to keystrokes, same as man page (UP-low). 3. update a filename reference to reality.

2019-06-22Add a direct pointer from struct prefix to struct pt_entry.claudio6-58/+61
This changes makes it possible to not use the struct rib_entry pointer which will be used to optimize the Adj-RIB-Out. Also adjust pt_ref() and pt_unref() so that the code can be written a bit more compact. Also prefix_cmp() no longer needs to go via rib_compare() and calls pt_prefix_cmp() directly. OK phessler@

2019-06-21Prevent recursions by not deleting entries inside rtable_walk(9).mpi10-81/+141
rtable_walk(9) now passes a routing entry back to the caller when a non zero value is returned and if it asked for it. This allows us to call rtdeletemsg()/rtrequest_delete() from the caller without creating a recursion because of rtflushclone(). Multicast code hasn't been adapted and is still possibly creating recursions. However multicast route entries aren't cloned so if a recursion exists it isn't because of rtflushclone(). Fix stack exhaustion triggered by the use of "-msave-args". Issue reported by Dániel Lévai on bugs@ confirmed by and ok bluhm@.

2019-06-21Fix conversions to long double on sparc64jca2-12/+12
Bug exposed by erratic sqlite3 behavior used in ports/devel/proj, as pointed out by landry@. Richard Hipps (SQLite) pointed at the culprit (_Qp_div), many thanks. Adapted from FreeBSD revision 146673 by Stephen Paskaluk and stefanf@FreeBSD. FreeBSD commit message: """ Fix long (and long long) to long double, unsigned to long double and unsigned long (and unsigned long long) to long double conversions. - Add a parameter that specifies the position of the sign bit to the _QP_TTOQ macro, previously it always looked at bit 31. Pass a negative number to disable sign inspection for unsigned types. This fixes _Qp_xtoq(), _Qp_uitoq() and _Qp_uxtoq(). - In the functions __fpu_itof() and __fpu_xtof(), look at the sign bit to decide whether we're doing a conversion from an unsigned type. If so, don't negate the mantissa if the integer exceeds the biggest signed number. """ ok deraadt@

Use install -F to instead of cp, for fsync(2). Coupled with the new sync(8) in the reorder_kernel script, the window for a incomplete /bsd file on-disk due to a crash has now shrunk substantially. Discussion with kettenis, millert and tedu

of resource limit structs has been done between processes. By applying copy-on-write also between threads, threads can read rlimits in a nearly lock-free manner. Inspired by code in DragonFly BSD and FreeBSD. OK mpi@, agreement from jmatthew@ and anton@

2019-06-21Add protection for private keys at rest in RAM against speculationdjm11-41/+324
and memory sidechannel attacks like Spectre, Meltdown, Rowhammer and Rambleed. This change encrypts private keys when they are not in use with a symmetic key that is derived from a relatively large "prekey" consisting of random data (currently 16KB). Attackers must recover the entire prekey with high accuracy before they can attempt to decrypt the shielded private key, but the current generation of attacks have bit error rates that, when applied cumulatively to the entire prekey, make this unlikely. Implementation-wise, keys are encrypted "shielded" when loaded and then automatically and transparently unshielded when used for signatures or when being saved/serialised. Hopefully we can remove this in a few years time when computer architecture has become less unsafe. been in snaps for a bit already; thanks deraadt@ ok dtucker@ deraadt@

2019-06-20Undefined behavior (UB) can potentially be present anywhere in theanton2-219/+396
kernel. kubsan reports findings using printf() and assuming that calling printf() is safe in all contexts can be problematic. Instead, defer reporting of findings to the systq task queue. Storage for findings is allocated early in the boot process in order to catch potential UB during boot. The same findings are reported once the task queue subsystem has been initialized.

2019-06-20Change nexthop_update to run the list walk over all prefixes to runclaudio3-57/+123
asynchronously and therefor other tasks can make progress at the same time. Additionally prefixes belonging to a RIB which does not run the the decision process are no longer linked into the nexthop list. This replaces the early return in prefix_updateall() and reduces the time spent in nexthop_update(). OK benno@
