2017-11-24Fix purging of modules with "fake literals"Björn Gustavsson
When compiling Erlang source code, the literal area for the module can only contain data types that have a literal syntax. However, it is possible to sneak in other data types (such as references) in the literal pool by compiling from abstract or assembly code. Those "fake literals" would work fine, but would crash the runtime system when the module containing the literals was purged. Although fake literals are not officially supported, the runtime should not crash when attempting to use them. Therefore, fix the garbage collection of literals and releasing of literal areas. https://bugs.erlang.org/browse/ERL-508

The retry loop wasn't working anyway as it tested fd<0 instead of res. So, there is no real semantic change here.

2017-11-20Fix max atom size overflow on 64-bits Erlang by lowering theBoshan Sun
MAX_ATOM_TABLE_SIZE Currently, the max atom size on 64-bits Erlang is ((UWORD_CONSTANT(1) << 32) = 4294967296 This number will cause the range of atom size to be displayed as [8192-0]. Also, the +t option for max atom size will be parsed as a long type, and assigned to a int variable erts_atom_table_size (erl_init.c), which will cause integer overflow if the number is larger than the maximum value a 4-bytes signed integer can hold ((1 << 31) - 1) = 2147483647 Therefore, during the comparison erts_atom_table_size < MIN_ATOM_TABLE_SIZE any number above 2147483647 will be come negative, and causing the condition to be true, which then errored out as bad atom table size. Hence, the actual max atom size is same as the max signed int value.
2017-11-20Fix integer overflow when set a large maximum value for atom tableBoshan Sun
When setting maximum atom table size using +t option, there will be a integer overflow for a large size. $ erl +t2147482625 ll_alloc: Cannot allocate 18446744073692774400 bytes of memory (of type "atom_tab"). The overflow is caused by the arithmetic operations on int type. When 2147482625 + 1024 it will become -2147483647 due to the signed integerger overflow. Then the result will be resized to Uint type, which is a unsigned long type, the negative int will first be expand to 64 bits long via sign extension, then change to unsigned type, which becomes 18446744073692774400. The fix is done by convert `limit` to Uint type before doing any arithmetic operation. This will expand variable to 64 bits long type via zero extension, then the following operation are all positive, therefore no overflow will happen. Note: here we assume the int `limit` passed in is always positive. If some future change cause the `limit` passed in maybe negative, then the current fix will also cause overflow.

2017-11-13Remove invalid EINTR loop around close(2)John Högberg
Retrying close(2) on anything other than HP-UX is likely to close something entirely different. POSIX says that the state of the file descriptor is unspecified, and Linux/BSD guarantee that it's closed on return.
