| 2003-12-10 | dstkva is not a pointer, so comparison with NULL is inappropriate. | Jun-ichiro itojun Hagino | |

| 2003-11-18 | faster pools. split pagelist into full, partial, and empty so we find what | Ted Unangst | |
| we're looking for. change small page_header hash table to a splay tree. from Chuck Silvers. tested by brad grange henning mcbride naddy otto | |||

| 2003-11-08 | Avoid a race condition while swapping in a process. | Thomas Nordin | |
| Tested by mickey@, henning@, ericj@, and beck@. ok mickey@ | |||
| 2003-10-08 | randomize return from uvm_map_hint. the random increment is limited | Ted Unangst | |
| to prevent fragmentation. this has the effect of randomizing unhinted mmap()s, sysV mem, and position of ld.so. tested on many archs by many developers for quite some time. use of MIN to allow m68k to play from miod@. vax is not included. ok deraadt@ miod@ | |||
| 2003-09-03 | m68k at least doesn't like random mappings. disable for now. | Ted Unangst | |
| i386 exec mappings are still random. detected by pvalchev@. ok deraadt@ | |||
| 2003-09-02 | add a random offset to uvm_map_hint. this has the primary effect of | Ted Unangst | |
| scattering ld.so and libraries around, although all mmaps will also have some jitter too. better version after some discussion with drahn testing/ok deraadt henning marcm otto pb | |||
| 2003-09-01 | match syscallargs comments with reality | Henning Brauer | |
| from Patrick Latifi <patrick.l@hermes.usherb.ca> ok jason@ tedu@ | |||
| 2003-08-15 | change arguments to suser. suser now takes the process, and a flags | Ted Unangst | |
| argument. old cred only calls user suser_ucred. this will allow future work to more flexibly implement the idea of a root process. looks like something i saw in freebsd, but a little different. use of suser_ucred vs suser in file system code should be looked at again, for the moment semantics remain unchanged. review and input from art@ testing and further review miod@ | |||
| 2003-08-10 | Remove uvm_useracc(): misleading, gives a false sentiment of security, and | Miod Vallat | |
| eventually not used anymore. Conforming to art@'s evil plans. | |||
| 2003-08-06 | Remove some double semicolons (hmm, do two semis equal a maxi?). | Todd C. Miller | |
| I've skipped the GNU stuff for now. From Patrick Latifi. | |||
| 2003-07-21 | enforce restrictions on prot and flags to mprotect and mmap. invalid or | Ted Unangst | |
| undefined flags are now rejected instead of silently ignored. makes "unintentional" mprotect calls a touch harder. ok art@ deraadt@ jason@ | |||
| 2003-07-01 | add MAP_TRYFIXED, mostly to help emulate other systems. | Ted Unangst | |
| when set, uvm will not attempt to avoid a heap address, if requested. from todd vierling, via http://marc.theaimsgroup.com/?l=netbsd-tech-kern&m=105612525808607&w=1 | |||
| 2003-07-01 | remove sys_omquery. it was only used for two weeks, and you can't | Ted Unangst | |
| source upgrade from a system that used it anyway. ok art deraadt drahn | |||
| 2003-06-29 | quell a "not a pointer" warning by using 0x%lx instead of %p for a vaddr_t | Anil Madhavapeddy | |

| 2003-05-05 | Move exec base to 0x1c000000, exe/data gap to 512MB. Allows better | Dale Rahn | |
| interleave of exe/shared libs. Raise MAXDSIZ back to 1G. This change REQUIRES a binary update on i386. | |||
| 2003-05-01 | typos; | Jason McIntyre | |
| ok art@ | |||
| 2003-04-28 | Change mquery() function call signature to be the same a mmap(). It | Dale Rahn | |
| needs the prot/flags info and passing the addresses via arg/return allows it to be traced via ktrace better than an in/out paramter. This adds a new mquery syscall and renames the old one to omquery. New kernel _MUST_ be built, booted, and 'make includes' before building ld.so with this change. | |||
| 2003-04-25 | backout mquery change, something broke when not combined with a different diff. | Dale Rahn | |
| 2003-04-25 | change mquery() function call signature to be the same a mmap(). It | Dale Rahn | |
| needs the prot/flags info and passing the addresses via arg/return allows it to be traced via ktrace better than an in/out paramter. This adds a new mquery syscall and renames the old one to omquery. New kernel _MUST_ be built and installed before building ld.so with this change. ok millert@ tedu@ | |||
| 2003-04-18 | Return EINVAL if MAP_FIXED was specified but was not available. ok tedu@ | Dale Rahn | |
| 2003-04-17 | changes to support mquery with 1Gsep on i386. avoid heap on mappings. | Dale Rahn | |
| 2003-04-14 | There are two related changes. | Artur Grabowski | |
| The first one is an mquery(2) syscall. It's for asking the VM system about where to map things. It will be used by ld.so, read the man page for details. The second change is related and is a centralization of uvm_map hint that all callers of uvm_map calculated. This will allow us to adjust this hint on architectures that have segments for non-exec mappings. deraadt@ drahn@ ok. | |||

| 2003-03-04 | do not treat map entries above the stack as stack; only for the grow-ups | Michael Shalayeff | |
| 2003-02-18 | fix the way stack is written into the core file on the upward growing stack ↵ | Michael Shalayeff | |
| machines. the other case is not affected. miod@ deraadt@ ok | |||
| 2003-01-29 | check the uvm_fault_wire() for failure, just like other calls; art@ ok | Michael Shalayeff | |
| 2003-01-09 | Remove fetch(9) and store(9) functions from the kernel, and replace the few | Miod Vallat | |
| remaining instances of them with appropriate copy(9) usage. ok art@, tested on all arches unless my memory is non-ECC | |||
| 2002-12-20 | user-defined stacks check is the same for grownups as for growndowns | Michael Shalayeff | |
| 2002-12-19 | simplify stack grownups (growndowns are not touched) | Michael Shalayeff | |
| 2002-12-09 | Two splasserts in map entry allocation. | Artur Grabowski | |
| 2002-11-19 | Use queue.h macros | Jason Wright | |
| 2002-11-08 | Don't uvm_useracc and then vslock. vslock is better at finding illegal mappings. | Artur Grabowski | |
| 2002-11-06 | Eliminate the use of KERN_SUCCESS outside of uvm/ | Artur Grabowski | |
| Also uvm_map returns KERN_* codes that are directly mapped to errnos, so we can return them instead of doing some attempt to translation. drahn@ "I see no problem" pval@ "makes sense" | |||
| 2002-10-29 | Since memory deallocation can't fail, remove the error return from | Artur Grabowski | |
| uvm_unmap, uvm_deallocate and a few other functions. Simplifies some code and reduces diff to the UBC branch. | |||
| 2002-10-29 | "len = entry->end - entry->start;" then logically "entry->start + len" | Artur Grabowski | |
| should be equal to "entry->end". (len is never changed) | |||
| 2002-10-17 | - name in uvm_tree_sanity must be const. | Artur Grabowski | |
| - fix a typo in comment. - enable uvm_tree_sanity ifdef DEBUG | |||
| 2002-10-12 | Remove more '\n's from panic() statements. Both trailing and leading. | Kenneth R Westerback | |
| Diff generated by Chris Kuethe. | |||
| 2002-10-07 | this removes the functionality of adding allocated | Michael Shalayeff | |
| pages into the queue already containing allocated pages. breaks i386:setup_buffers() because of this. | |||
