This can be tested by giving the following test program a # filename in an AFS directory: # # #include <stdio.h> # #include <stdlib.h> # #include <unistd.h> # #include <fcntl.h> # #include <sys/mman.h> # int main(int argc, char argv[]) # { # char p; # int fd; # if (argc != 2) { # fprintf(stderr, # "Format: test-trunc-mmap <file>\n"); # exit(2); # } # fd = open(argv[1], O_RDWR \| O_CREAT \| O_TRUNC); # if (fd < 0) { # perror(argv[1]); # exit(1); # } # if (ftruncate(fd, 0x140008) == -1) { # perror("ftruncate"); # exit(1); # } # p = mmap(NULL, 4096, PROT_READ \| PROT_WRITE, # MAP_SHARED, fd, 0); # if (p == MAP_FAILED) { # perror("mmap"); # exit(1); # } # p[0] = 'a'; # if (munmap(p, 4096) < 0) { # perror("munmap"); # exit(1); # } # if (close(fd) < 0) { # perror("close"); # exit(1); # } # exit(0); # } # # Fixes: 31143d5d515e ("AFS: implement basic file write support") # Reported-by: Jonathan Billings <jsbillin@umich.edu> # Tested-by: Jonathan Billings <jsbillin@umich.edu> # Signed-off-by: David Howells <dhowells@redhat.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 8c7ae38d1ce12a0eaeba655df8562552b3596c7f # < make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # make -s -j 48 ARCH=mips O=/kisskb/build/linus_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] In file included from /kisskb/src/include/linux/printk.h:7:0, from /kisskb/src/include/linux/kernel.h:15, from /kisskb/src/include/linux/fs_context.h:15, from /kisskb/src/fs/fs_parser.c:13: /kisskb/src/fs/fs_parser.c: In function 'fs_validate_description': /kisskb/src/include/linux/kern_levels.h:5:18: warning: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'int' [-Wformat=] #define KERN_SOH "\001" /* ASCII Start Of Header / ^ /kisskb/src/include/linux/kern_levels.h:11:18: note: in expansion of macro 'KERN_SOH' #define KERN_ERR KERN_SOH "3" / error conditions */ ^ /kisskb/src/include/linux/printk.h:302:9: note: in expansion of macro 'KERN_ERR' printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__) ^ /kisskb/src/fs/fs_parser.c:413:6: note: in expansion of macro 'pr_err' pr_err("VALIDATE %s: e[%lu] enum val for %s\n", ^ <stdin>:1478:2: warning: #warning syscall pidfd_send_signal not implemented [-Wcpp] <stdin>:1481:2: warning: #warning syscall io_uring_setup not implemented [-Wcpp] <stdin>:1484:2: warning: #warning syscall io_uring_enter not implemented [-Wcpp] <stdin>:1487:2: warning: #warning syscall io_uring_register not implemented [-Wcpp] FIT description: Linux 5.1.0-rc2-g8c7ae38d1ce1 Created: Fri Mar 29 08:41:58 2019 Image 0 (kernel@0) Description: Linux 5.1.0-rc2-g8c7ae38d1ce1 Created: Fri Mar 29 08:41:58 2019 Type: Kernel Image Compression: gzip compressed Data Size: 4546841 Bytes = 4440.27 KiB = 4.34 MiB Architecture: MIPS OS: Linux Load Address: 0x80100000 Entry Point: 0x808675f0 Hash algo: sha1 Hash value: 71152646b77934eb63767069f80433714b85b7f5 Image 1 (fdt@boston) Description: img,boston Device Tree Created: Fri Mar 29 08:41:58 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 3793 Bytes = 3.70 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 4799f50d688573234da6e9d7701234d394759ef4 Image 2 (fdt@ni169445) Description: NI 169445 device tree Created: Fri Mar 29 08:41:58 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 1871 Bytes = 1.83 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 51b89b31605ee62038c8468c429af091dfc75ec7 Image 3 (fdt@xilfpga) Description: MIPSfpga (xilfpga) Device Tree Created: Fri Mar 29 08:41:58 2019 Type: Flat Device Tree Compression: uncompressed Data Size: 2708 Bytes = 2.64 KiB = 0.00 MiB Architecture: MIPS Hash algo: sha1 Hash value: 63d058b780f65e22da30f0a183433765f1807f1d Default Configuration: 'conf@default' Configuration 0 (conf@default) Description: Generic Linux kernel Kernel: kernel@0 Configuration 1 (conf@boston) Description: Boston Linux kernel Kernel: kernel@0 FDT: fdt@boston Configuration 2 (conf@ni169445) Description: NI 169445 Linux Kernel Kernel: kernel@0 FDT: fdt@ni169445 Configuration 3 (conf@xilfpga) Description: MIPSfpga Linux kernel Kernel: kernel@0 FDT: fdt@xilfpga Completed OK # rm -rf /kisskb/build/linus_mips-defconfig_mipsel # Build took: 0:01:28.749823
