int mprotect ( void *addr , size_t len , int prot );. DESCRIPTION.

mprotect() works internally by altering the flags attached to a VMA 2. The first thing it must do is look up the VMA corresponding to the address that was passed - if the passed address was within the kernel's address range, then there is no VMA, and so this search will fail.

xv6 loosely follows the structure and style of v6, but is implemented for a modern x86-based multiprocessor using ANSI C. ACKNOWLEDGMENTS xv6 is inspired by John Lions's Commentary on UNIX 6th Edition (Peer to Peer Communications; ISBN: 1-57398-013-7; 1st edition (June 14 Generated on 2019-Mar-29 from project linux revision v5.1-rc2 Powered by Code Browser 2.1 Generator usage only permitted with license.

(beyond the fact that 0 means "no error" for both). In standard C, the only portable arguments to exit() are 0, EXIT_SUCCESS, and EXIT_FAILURE. If you're not concerned with portability to all C implementations (and since you're using mprotect(), presumably you're not), you can use other values, but errno values aren't necessarily sensible.

SYNOPSIS. #include int mprotect(const void *addr, size_t len, int prot); est toujours consultable via la commande : « LANG=C man 2 m 30 May 2020 at mmap/mprotect time with a new protection flag PROT_NOSYSCALL. mm/ mprotect.c | 2 +- 8 files changed, 97 insertions(+), 2 deletions(-)  Я написал небольшую часть программы на C, затем скомпилировал и выполнил У меня еще есть вопрос о mprotect и отсутствие флага выполнения. 2020年7月1日 在Linux中，mprotect()函数可以用来修改一段指定内存区域的保护属性。 函数原型 如下： #include 分类: linux, c/c++. 好文要顶 关注我 收藏该文. strace -c.

The fruit of this consolidation is that mprotect now merges file-backed vmas naturally. LSM BPF Programs¶. These BPF programs allow runtime instrumentation of the LSM hooks by privileged users to implement system-wide MAC (Mandatory Access Control) and Audit policies using eBPF. mprotect() Change memory protection. Synopsis: #include int mprotect( const void * addr, size_t len, int prot); Arguments: addr The beginning of the range of addresses whose protection you want to change.

Here is a tutorial on how to accomplish this: Writing a Self-Mutating x86_64 C Program; from the notes on the mprotect manual page: On Linux it is always permissible to call mprotect() on any address in a process's address space (except for the kernel vsyscall area). In particular it can be used to change existing code mappings to be writable.
