* Add strndup(3) prototype to string.h.Konstantin Belousov2008-12-082-2/+2
| | | | | | | | | | | | | | This change was erronously ommitted from the r185690, and attempt to simply add the prototype to string.h has revealed that several contributed programs defined local prototypes for strndup(), controlled by autoconfed config.h. So, manually change #undef HAVE_STRNDUP to #define HAVE_STRNDUP 1. Next import of the corresponding program would regenerate config.h, overriding the changes in this commit.

* When libthr and rtld start up, there are a number of magic spells castPeter Wemm2008-12-071-1/+1
| | | | | | | | | | | | | | | | | in order to get the symbol binding state "just so". This is to allow locking to be activated and not run into recursion problems later. However, one of the magic bits involves an explicit call to _umtx_op() to force symbol resolution. It does a wakeup operation on a fake, uninitialized (ie: random contents) umtx. Since libthr isn't active, this is harmless. Nothing can match the random wakeup. However, valgrind finds this and is not amused. Normally I'd just write a suppression record for it, but the idea of passing random args to syscalls (on purpose) just doesn't feel right. Notes: svn path=/head/; revision=185728

* MfP4: Big read filter refactoring.Tim Kientzle2008-12-0615-1550/+1427
| | | | | | | | | | | | | | | | | | | | | | | | | | This is an attempt to eliminate a lot of redundant code from the read ("decompression") filters by changing them to juggle arbitrary-sized blocks and consolidate reblocking code at a single point in archive_read.c. Along the way, I've changed the internal read/consume API used by the format handlers to a slightly different style originally suggested by des@. It does seem to simplify a lot of common cases. The most dramatic change is, of course, to archive_read_support_compression_none(), which has just evaporated into a no-op as the blocking code this used to hold has all been moved up a level. There's at least one more big round of refactoring yet to come before the individual filters are as straightforward as I think they should be... Notes: svn path=/head/; revision=185679

The change is totally unintrusive, essentially made of a single function to be called while parsing a dhcp response, and a couple of tables to classify options. The values extracted from dhcp options are stored in the kenv environment in one of these forms: + options whose name and type is known are saved as dhcp.name = value (string, or number/ip addresses lists) + unknown options are assumed to be strings and saved as dhcp.option-NNN = "value" + options listed as '__INDIR' and sent on the wire as e.g. option unknown-252 "some.name=the actual value" are saved as some.name = "the actual value" + options listed as '__ILIST' and sent on the wire as e.g. option unknown-249 "a.b=foo bar; c.d= 123; e.f=done" are saved as multiple values a.b="foo bar" c.d="123" e.f="done" As you can see there is quite a bit of flexibility on what can be passed to the loader or the kernel. For the time being the vendor-specific table is mostly disabled, because there is no standard set of options for FreeBSD, and I don't know all the pxe-specific vendor options. Also, applications using libstand may live in memory-constrained environments, so it makes sense to keep these tables as small as possible, especially considering that one can generate arbitrary name=value pairs using site-specific options of type __INDIR or __ILIST (there are 4 __ILIST and 5 __INDIR in the table, numbered 246..249 and 250..254). Actually, considering that probably 75% of the standard dhcp options are totally useless, it might make sense to remove them as well.

* Merge user/peter/kinfo branch as of r185547 into head.Peter Wemm2008-12-024-1/+152
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes struct kinfo_filedesc and kinfo_vmentry such that they are same on both 32 and 64 bit platforms like i386/amd64 and won't require sysctl wrapping. Two new OIDs are assigned. The old ones are available under COMPAT_FREEBSD7 - but it isn't that simple. The superceded interface was never actually released on 7.x. The other main change is to pack the data passed to userland via the sysctl. kf_structsize and kve_structsize are reduced for the copyout. If you have a process with 100,000+ sockets open, the unpacked records require a 132MB+ copyout. With packing, it is "only" ~35MB. (Still seriously unpleasant, but not quite as devastating). A similar problem exists for the vmentry structure - have lots and lots of shared libraries and small mmaps and its copyout gets expensive too. My immediate problem is valgrind. It traditionally achieves this functionality by parsing procfs output, in a packed format. Secondly, when tracing 32 bit binaries on amd64 under valgrind, it uses a cross compiled 32 bit binary which ran directly into the differing data structures in 32 vs 64 bit mode. (valgrind uses this to track file descriptor operations and this therefore affected every single 32 bit binary) I've added two utility functions to libutil to unpack the structures into a fixed record length and to make it a little more convenient to use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bring in updated jail support from bz_jail branch. This enhances the current jail implementation to permit multiple addresses per jail. In addtion to IPv4, IPv6 is supported as well. Due to updated checks it is even possible to have jails without an IP address at all, which basically gives one a chroot with restricted process view, no networking,.. SCTP support was updated and supports IPv6 in jails as well. Cpuset support permits jails to be bound to specific processor sets after creation. Jails can have an unrestricted (no duplicate protection, etc.) name in addition to the hostname. The jail name cannot be changed from within a jail and is considered to be used for management purposes or as audit-token in the future. DDB 'show jails' command was added to aid debugging. Proper compat support permits 32bit jail binaries to be used on 64bit systems to manage jails. Also backward compatibility was preserved where possible: for jail v1 syscalls, as well as with user space management utilities. Both jail as well as prison version were updated for the new features. A gap was intentionally left as the intermediate versions had been used by various patches floating around the last years. Bump __FreeBSD_version for the afore mentioned and in kernel changes. Special thanks to: - Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches and Olivier Houchard (cognet) for initial single-IPv6 patches. - Jeff Roberson (jeff) and Randall Stewart (rrs) for their help, ideas and review on cpuset and SCTP support. - Robert Watson (rwatson) for lots and lots of help, discussions, suggestions and review of most of the patch at various stages. - John Baldwin (jhb) for his help. - Simon L.

In these CPUs, the actual numbers, kinds and widths of PMCs present need to queried at run time. Support for specific "architectural" events also needs to be queried at run time. Model 0xE CPUs support programmable PMCs, subsequent CPUs additionally support "fixed-function" counters. - Use event names that are close to vendor documentation, taking in account that: - events with identical semantics on two or more CPUs in this family can have differing names in vendor documentation, - identical vendor event names may map to differing events across CPUs, - each type of CPU supports a different subset of measurable events. Fixed-function and programmable counters both use the same vendor names for events. The use of a class name prefix ("iaf-" or "iap-" respectively) permits these to be distinguished. - In libpmc, refactor pmc_name_of_event() into a public interface and an internal helper function, for use by log handling code. - Minor code tweaks: staticize a global, freshen a few comments.
