| | | | | | | | | * storeio.c (parse_opt): Set PARAMS->store_params.store_optional. (storeio_fsys): New global variable. (main): Use it. * dev.h: Declare it. * dev.c (dev_open): If DEV->store_name is null, open the underlying node using store_create.
* * Makefile (HURDLIBS): Reorder libs such that the threads libMark Kettenis2000-07-262-2/+9
| | | | | | comes before the ports lib. This makes sure the functions in libthreads properly override the stubs in libports with the new dynamic linker semantics in glibc 2.2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | * dev.h (struct dev): New members store_name, readonly, rdev. (dev_is_readonly): New inline function. * dev.c (dev_open): Take just one arg, a struct dev whose store==0. (dev_close): Shut down the store, but leave DEV intact with store==0. * storeio.c (struct storeio_argp_params): New type. (device, device_lock, store_name): Variables removed. (readonly, inhibit_cache, enforce_store, rdev): Likewise. These are all now members in struct storeio_argp_params or struct dev; rdev now uses dev_t instead of int. (parse_opt): Find a struct storeio_argp_params in STATE->input and fill it in accordingly. Use makedev macro to construct rdev. (trivfs_append_args): Find options in struct dev off control hook. Use major, minor macros. (main): Make DEVICE a local here, and point FSYS->hook at it. Don't modify trivfs_allow_open. (getroot_hook): New static function. (trivfs_getroot_hook): New variable, initialized to that. (check_open_hook): Find struct dev in CNTL->hook and use new dev_open interface. Use dev_is_readonly. (open_hook): Find struct dev in PEROPEN->cntl->hook and check DEV->store. (trivfs_modify_stat): Find struct dev in CRED->po->cntl->hook. Use dev_is_readonly. (trivfs_goaway): Find struct dev in FSYS->hook and use its lock. (trivfs_S_fsys_syncfs): Find struct dev in CNTL->hook.

| | | | | * storeio.c (trivfs_modify_stat): Clear writable bits if open store is readonly, not just if we got the --readonly switch.

| | | | | | | * dev.c (dev_read, dev_write): In DEV->inhibit_cache case, handle zero (i.e. unknown) block_size by treating it as 1. Use shift and bitwise-and rather than multiply and modulus for block size arithmetic, since it's a known power of two.

(options, parse_opt, trivfs_append_args): Grok new option --enforced/-e to set enforce_store. (check_open_hook): Set DEVICE->enforced from enforce_store. * io.c (trivfs_S_file_get_storage_info): If DEV->enforced is set and the store flags lack STORE_ENFORCED, then return STORAGE_OTHER.

| | | | | | | | | | | | * storeio.c (check_open_hook): Don't check for D_NO_SUCH_DEVICE here.
